PREFACE

The API Well Number is a unique, permanent, numeric identifier assigned for identification purposes to a well (hole-in-the-ground) which is drilled for the purpose of finding or producing oil and/or gas or providing related services. To date, over one million wells in the United States have been assigned these identity numbers.

API Well Numbers are usually available on "current wells" from the regulatory state or federal agencies who assign the number. On "historic wells" the numbers can be obtained from service companies or cooperative groups who originally assigned the numbers to these wells. "Historic wells" are defined as those drilled prior to some specifically established date and "current wells" are those drilled subsequent to that date, Th'ese reference dates are provided in Section VI1 in the contact paragraph for each regulatory agency.

The bulletin is organized in the following sections: Section I - The purpose, code structure, and use of the API Well Number; also, definitions for the various hole identifications.

Section II - Diagrams that illustrate the proper methods of number assignment. Section III - Regulatory procedures for assignment of the numbers. Section IV - Origin of state and county numeric codes. Section V - Maps and descriptions of the states, pseudo-states, offshore state waters, and offshore federal waters, Section VI - State and pseudo-state numeric codes. Section VI1 - County and pseudo-county numeric codes for each state. Section VI11 - Pseudo-county numeric codes for offshore federal waters. Section IX - Codes for Mexico. Section X - General codes for undesignated waters.

Foreword

This bulletin, compiled by the Subcommittee on Well Data Retrieval Sys- tems, is published under the jurisdiction of the API Executive Committee on Drilling and Production Practice. The original report of the Subcommittee on Well Data Retrieval Systems was adopted and published as Appendix A, API BULLETIN D12, April 1966, WELL DATA GLOSSARY. Appendix A was superseded by API BULLETIN D12A, April 1968, THE API WELL NUMBER AND STANDARD STATE AND OUNTY CODES. A revised edition of BULLETIN D12A was published December 1970, Supplement 1 published September 1974 extended the coding to cover the Northern Gulf of Mexico offshore.

This new edition, January 1979, extends the coding to all North American offshore waters including those adjacent to Mexico. It also contains revisions in the text and therefore supersedes the foregoing editions and supplements

Acknowledgment

The API Subcommittee on Well Data Retrieval Systems was formed in 1962 to achieve as much compatibility as possible between cooperative well data systems. A primary objective of the Subcommittee was to develop a standard method of nationwide identification of wells for use in computer well data systems.

The Subcommittee acknowledges the numerous contributions from Co-workers, computer systems analysts, geologists, and engineers for their part in the final development of the ideas presented in this report. These individuals were involved because of their work with various industry cooperative computer well data systems and with their own proprietary data systems. Special appre- ciation is expressed to the Advisory Members from the federal government and from state regulatory agencies for their participation and advice.

SECTION I

THE API \JELL NUMBER

ITS PURPOSE, CODE STRUCTURE, AND USE

Introduction

The oil and gas industry is making large scale use of computers to handle data on wells in day-to-day operations. This is also true for many state and federal oil and gas regulatory agencies. Some states and some departments of the federal government accept much of their required regulatory data on either punched cards or magnetic tape from the oil and gas industry. Many service companies, data gathering agencies, and professional organizations are using computer systems to store and process well data.

A need common to all of these organizations is a simple, consistent method for identifying all wells--an identity that will not change through time and an identity that will not change with various well operations.

1/1/79 -5- BULL D12A-79 -3 0732290 0005188 8

It is imperative that each well (i.e., hole-in-the-ground) be uniquely identified in order for computer-oriented data to be most useful to industry, government, and educational institutions, This unique identity must be fixed and unchangeable throughout time. This is not true for the historical method normally used for well identification, which is operator name, lease name, and lease well number--each of these data elements is subject to change during the life of a well.

Computers do not work efficiently with this historical method of well identification--first, because of constant changes and second, because almost all of the data is alphabetic, An assigned numeric code is the most effective solution, To this end, the American Petroleum Institute Subcommittee on Well Data Retrieval Systems recommends a numbering scheme applicable to all wells in North America. This numbering method results in each well (hole-in-the- ground) being assigned a number which is never duplicated and is applicable throughout time. It is termed the API Well Number; its sole purpose is to uniquely identify the drilled hole.

To date over one million wells have been assigned identity numbers based on this method through the combined efforts of the various industry groups and governmental agencies. The regional cooperative well data systems have agreed to make the numbers on historical wells available to state or federal regulatory agencies and to industry. The MI Well Number is a means whereby any company, governmental agency, or other group may interrelate or exchange well data from all logical geographic, geological, or arbitrary areas. The handling of well data is expedited by having this identifier which is of standard format and will never change, regardless of changes in ownership, descriptive location, recompletion, unitization, or abandonment.

Use of the API Well Number is recommended as a standard practice for the unique identification of wells by industry and government.

The Federal Government is using the API Well Number as a control number and as an identifier and reference. The Federal Energy Regulatory Commission (FERC) of the Department of Energy (DOE) requests the entry of the API Well Number on its form (FERC 121), for the identification of wells. The data on this form are used to establish wellhead prices for natural gas, The data are submit'ted to both the appropriate regulatory state agency and to FERC accord- ing to regulations established under the Natural Gas Policy Act of 1978 (HR 5289).

The Code Number Structure

The API Well Number is a control number for a well. The original hole from total depth to surface is identified by a .ten-digit number consisting of three parts--the state code, the county code, and the unique well code. When a well is directionally sidetracked, a fourth code of two digits is added.

API WELL NUMBER

DIRECTIONAL ORIGINAL HOLE SIDETRACK

STATE UNIQUE SIT CODE -:E? I WELL CODE CODE 99 999 I 99999 99

Note: The API Well Number is a numeric control; therefore, alphabetic or special characters cannot be used in any positions in the code.

a. State Code--Two numeric digits.

Refer to Section VI, pp. 64-65, for the complete list of state codes and pseudo-state codes. This list provides codes for both onshore and offshore United States, Canada, and Mexico.

b. County Code--Three numeric digits.

Refer to Section VII, pp. 66-113, for complete lists of onshore county codes (including parish codes for Louisiana, and U.S.G.S. quadrangles for Alaska) and pseudo-county codes for offshore state waters. Refer to Section VIII, pp. 116-133, for pseudo-county codes for offshore waters of North America. Discussion for origin of offshore pseudo-county codes is found in Section IV, pp. 24-28. Descriptions and maps for the onshore and offshore areas are found in Section V, pp. 29-57.

C. Unique Well Code--Original Hole--Five numeric digits.

These well codes are assigned as unique numbers within each county from 1 to 60000. In many states, these numbers are assigned serially. The various cooperative well data groups agreed to assign numbers 1-20000 for historical wells; governmental regulatory agencies start to assign at number 20001 for current and future wells, (Exceptions to this procedure are discussed on page 22 and in Section IV, pp. 24-28, and in the contact paragraphs for the individual states in Section VII, pp. 66-113.)

-7- 1/1/79 BULL D12A-79

d. Directional Sidetrack Code--Two numeric digits. In order that directional sidetrack holes can be related to the original hole and uniquely identified, a two-digit suffix, assigned serially, is added to the original well number. Some data systems require that these two digits be zero filled on the original hole; other systems accept blanks. This should be an option of the user. The recommended numeric codes for states, pseudo-states, counties, and pseudo-counties listed in Sections VI through VIII, pp. 64-135, are the result of continuing work by various industry committees over the past 25 years. One of the earliest publications of these codes was by IBM in 1952. Subsequent manuals with recommended standard state and county codes have been published by the Committee for Statistics on Drilling (CSD) of the American Association of Petroleum Geologists (AAPG) and the API Subcommittee on Well Data Retrieval Systems. This current publication contains the latest revisions and additions recommended by American Petroleum Institute. These have been reviewed and accepted by advisory members of the above CSD of AAPG.

Definitions For Hole Identification Purposes

The following definitions are presented to prevent misunderstandings that occur as a result of semantics in discussing the assignment of API Well Num- bers as recommended in this publication. The APL Well Number identifies the hole. It does not offer any utility for identifying well status, classification of the well, bottom hole location, completion interval, or for delineating down-hole operations such as drill- deeper, plug-back, recompletion, treatment, rework, and remedial work. A. API Well Number--a unique numeric identifier for a hole-in-the-ground. The identifier is assigned on the basis of surface location and extends from the surface to total depth. B. -Well--the hole-in-the-ground drilled from the point of entry at the earth's surface to total depth of the hole. The well is normally drilled through a single and specific surface casing for the purpose of:(l) finding or producing crude oil or natural gas; or (2) providing services related to the production of crude oil or natural gas, Refer to Section III, page 21, "What Wells are Numbered," for discussions on wells that are not drilled primarily in search of crude oil or natural gas, such as geothermal, sulfur, and other prospect tests.

-8- 1/1/79 BULL D12A-79 u 0732290 0005191 ô I

C. Service Wells--a service well is one drilled or completed for the purpose of supporting production in an existing field. Wells of this class are drilled for the following purposes: gas injection (natural gas, flare gas, inert gas, propane, or butane), water injection, steam injection, air injection, salt water disposal, water supply for injection, and observation. In certain states, these service wells require API Well Number assignments. (Refer to discussion on page 21.)

D. Stratigraphic (Core) Test--a stratigraphic test is a drilling effort, geologically directed, to obtain information pertaining to specific geological conditions that might lead to the discovery of an accumu- lation of hydrocarbons. Such wells are drilled without the expec- tation of being completed for hydrocarbon production. This classification also includes tests identified as core tests by some operators.

E. Surface Casing--the shallowest casing string required to protect fresh water zones, to provide sufficient pressure control during drilling operations, and to support the wellhead. It is -not to be confused with a drilling conductor pipe nor with a large caisson in an offshore area which encloses several separate and unique surface cas- ings at the surface.

F. Controlled Directional Well (or Deviated Well)--a hole purposely deviated from the vertical in specific directions using controlled angles to reach an objective location (target) other than directly under the surface location.

G. Directional Sidetrack or Directional Redrill--(abbreviated as SIT)-- A drilling effort in which an additional hole is drilled by leaving a previously drilled hole at some depth below the surface and above the total depth. A whipstock is set in the previously drilled hole which is the starting point for the sidetracking operation. This section of new hole is directionally drilled to a new objective bottom hole location (target).

This sidetrack normally requires setting a directional-control tool (whipstock) in the old hole and requires controlled drilling tech- niques. The directional sidetrack is identified as the section of hole from the depth of the first sidetrack tool to total depth of the new hole. In the API Well Number, the two-digit suffix or sub-number identifies only the portion of the hole from the sidetrack tool to total depth; the complete API Well Number (original ten-digits plus suffix) identifies the entire hole from point of entry at the earth's surface to total depth of the sidetrack.

This directional sidetrack identity does not apply to remedial sidetrack operations in which portions of a hole are purposely detoured around junk, redrill of "lost hole," or straightening "key seats" and "crooked holes. I'

Refer to page 22 for an explanation on how to handle dual data using Reserved Sidetrack Codes.

H. Offshore Well--an offshore well is one which is bottomed at, or produces from, a point which lies seaward of the coastline. In general, the term coastline means the line of ordinary low water along that portion of the coast which is in direct contact with the open sea or the line marking the seaward limit of inland waters. If a state agency uses a different basis for classifying onshore and offshore wells, the state classification is used. As an example, for purposes of statistical reporting Cook Inlet (Alaska) is classified as off shore.

These definitions relating to hole identity conform to those published by API Department of Statistics. For more complete discussions and definitions of terms related to wells, refer to: STANDARD DEFINITIONS FOR PETROLEUM STATISTICS, API Technical Report No. 1, API Statistics Department, 2101 L Street, NW, Washington, D. C., 20037.

SECTION III

REGULATORY ASSIGNMENT OF API WELL NUMBERS

REGULATORY CONTROL

The American Petroleum Institute recommends that the appropriate state or federal regulatory agency administer the assignment of the API Well Number.

Drilling Permits--In states or in offshore federal waters where a "drilling permit" system is used, it is recommended that the API Well Number be placed on the permit at the time the identification data is transcribed onto the cross-reference ledger. This procedure places these codes in the hands of the operator, scouting and data gathering organizations, and related service contractors at the earliest date. It is also cross referenced on appropriate documents in the regulatory agency files.

Publication--In those states or federal offices which periodically publish listings of permits issued, the inclusion of API Well Numbers and all other related identification data is appropriate and desirable. This publication becomes the means whereby the various data systems, scouting organizations, governmental agencies, educational institutions, and individual companies can obtain the API Well Number for reference and for inclusion in current computer files.

Unpublished--For states or federal offices which do not have a regular publication (or have a closed circulation) the availability of a cross- referenced ledger as a matter of public record will permit interested parties to obtain these codes. Commercial reporting services, oil scout organizations, and the oil and gas industry use the API Well Number as an integral part of their well identification, therefore these numbers are needed on a routine basis.

Spudding Reports--In those states or federal offices that require spudding reports, this may be the optimum time to assign the API Well Number because it assures identification of wells actually drilled. This elimi- nates a minor problem of numbers existing on wells that are never drilled.

Completion Reports Only--In states where a drilling permit or an intent-to- drill notice is not required and only a completion report (or plugging report for a dry hole) is filed with the appropriate regulatory agency, the API Well Number assignment should be placed on these records in the same manner as for drilling permits. The number should be placed on the record at the time identification data is entered on the cross-reference ledgers. The inclusion of the API Well Number as an integral part of any published listing of "New Completions", including "Dry Tests", would be appropriate.

-17- 1/1/79 BULL DL2A-79

Procedures for Regulatory Control of API Well Number

Assignments are made by state and federal regulatory agencies as a service to the oil and gas industry and, thus, is a matter of public record. To be most effective the assignment of this number must be both controlled and maintained by the regulatory agency.

Ledgers--A suggested practice is that state or federal offices maintain a set of uncomplicated ledger sheets, one for each county in which drilling occurs. These ledger sheets or cross-reference ledgers relate basic identification to the assigned API Well Number as follows:

API Well Number Operator Name (and other data Lease Name deemed appropriate) Lease Well Number Descriptive Location

The exact layout of a ledger page will vary with each regulatory agency but a typical list is illustrated as follows:

-18- 1/1/79 10732290 O005201 7 I

At the time the identity information is placed in such a ledger, the API Well Number is transferred to the appropriate permit, a copy of which is returned to the operator or to the completion report (or plugging report for dry holes), before filing in the regulatory records. Where completion or plugging reports are the only form on which the number is applied, a published record must show the number.

The regulatory body may make the assignment of the API Well Number at district offices, provided an adequately controlled method is established to communicate the number to the main office. Where such a district's boundary divides a county or parish, a special procedure will be needed to insure that the "Well Code" portion of the API Well Number remains unique. This unique- ness is best accomplished if the wells are numbered serially within the county.

Procedures For Error Corrections

When an error occurs in the assignment of numbers, such as a well being coded into the wrong county, corrections are accomplished in the same manner that new well assignments are made. Thus, the well is entered into the cross- reference ledger in the correct place, being assigned the next chronological or serial number, and placed on the next publication of "locations staked" or Il completions made" as a correction entry. The number which was erroneously assigned is canceled in the cross-reference ledger by simply marking through it and noting it "error", but not reassigning it to any future well. In many cases the scouts or data systems are the ones who first recognize the exis- tence of an error; they will notify the appropriate agency of these errors for necessary corrections to the files.

Duplicate Numbering Errors

The appearance of duplicate numbers indicates an error in number assignment. When these duplicates occur it is imperative that corrections be made and published as soon as possible. This type of error occurs in two different situations--1. Multiple Numbers and 2. Identical Number.

1. Multiple API Well Numbers Assigned--one well with two or more API Well Numbers (different numbers) assigned. This error is common when wells are deepened or sidetracked, and in both these situations the original API -Well Number is used- rather than assignment of a new number.

MULTIPLE API WELL NUMBERS t ~~~~~ ~~~~ 42-201-20001 ? I 42-201-20123

-19- 1/1/79 BULL D12A-79 4 0732290 0005202 9 I

To correct this type of error:

(a) OWDD--for old wells drilled deeper, the original API Well Number is the correct number assigned. The new number incorrectly assigned to the deepening operation is to be canceled. -Note: In the event the old well was never numbered in the "historic wells" then the current new number can be applied to both,

(b) Sidetrack--refer to Case 4 on page 12 for an illustration of the correct numbering procedure for sidetrack holes. When an erroneous new number is assigned to a sidetrack hole, it is changed to the correct original hole number with the proper two-digit suffix identity for the directional sidetrack.

(c) Multiple Numbers--occasionally an agency will assign two or more API Well Numbers to the same well. This usually occurs as a result of the refiling of drilling permits, changes in location prior to drilling, operator name changes, etc,

In some situatio-the last number assigned by the regulatory agency can be used if proper notification is made regarding the cancellation of earlier numbers.

Often, conflicting multiple numbers are best handled by cancellation of all numbers and none of the numbers should be reassigned or reused for any future wells. A -new API Well Number is assigned for the well in conflict.

2. Identical API Well Number Assigned to Wells--two or more wells (different wells) with an identical API Well Number.

IDENTICAL NUMBER WELLS 42-201-20555 ? 42-201-20555

To correct this error, the identical API Well Number for these wells is considered erroneously assigned and therefore canceled in the cross-reference ledger. This number should not be reassigned or reused for any future wells. -New API Well Numbers are assigned for each of the wells.

-20- 1/1/79 Publication of Errors--publication or appropriate notification of all errors and corrections should be made available to the public on a routine basis.

What Wells are Numbered

The prime application of the API Well Number is for data files maintained in connection with the search for and production of oil and gas.

The following type wells, which do not normally require a drilling permit, may or may not be assigned an API Well Number by the regulatory agencies.

1. Stratigraphic Tests and Core Tests--these are drilling efforts to obtain geological information with no intention of completion as a producer.

2. Water Supply Wells--wells drilled to produce water, either fresh or salty, for industrial use.

3. Water Disposal Wells--wells drilled to dispose of waste waters (usually salty). Water injection wells often serve as water disposal wells.

4. Water Injection Wells and Gas Injection Wells--wells utilized in conjunction with operations of an oil or gas reservoir for supplemental recovery. Thermal injection wells are a special type utilized in secondary recovery operations.

Note: When a former producing well is recompleted to convert it to an injection well, -no new number is assigned, but the work will be "systems correlated" with the original API Well Number. (Refer to Supplemental Well Operations on page 23.)

5. Sulfur Wells--wells drilled for the prime purpose of sulfur production.

6. Underground Storage Wells--wells drilled for the purpose of storing hydrocarbons underground in either the gaseous or liquid state in created caverns or natural reservoirs.

7. Geothermal Tests--wells drilled for the purpose of exploring for or producing geothermal energy.

8. Prospect Tests--holes drilled in prospecting for minerals such as uranium, coal, sulfur, etc.

When the regulatory agency requires drilling permits for any of these special types of wells, API Well Number assignments are recommended.

Well Code Number Ranne--Historical and Current Wells

Historical Wells--00001-20000

Current Wells----- 20001-60000

In most areas of active drilling, industry cooperative well data systems have assigned numbers to most of the historical wells (refer to page i for definitions of historic and current wells). Numbers 1-20000 for the unique well code have been reserved for the historic wells in most states. Some states have deviated from this recommended numbering system because of their own needs or previously established systems. For example, Illinois and North Dakota have no break between historical and current well numbers; Arkansas started current well numbers at 10001, Texas began numbering current wells at 30001. Colorado, Michigan, and Utah have special numbering systems. Wells in fede& waters offshore Texas and Louisiana started at 40001, For further details refer to the individual state information contained in Section VII, pp. 66-113.

Reserved Numbers 60001-95000

For wells which are not assigned a number by the regulatory agency, but are "information important" and therefore obtained for some appropriate data system, the system may assign numbers for well codes from the number series 60001 through 95000 in each county,

Exempt Numbers 95001-99999

The number series from 95001 to 99999 will not be used by regulatory agencies or cooperative systems. This series is reserved for proprietary use within any company system for wells that do not have API Well Numbers however are "information important" to the company.

Reserved State Codes

The state codes 71-89 are reserved for use by the Canadian Petroleum Association. Numbers 90-99 are reserved for internal use of the individual companies. Therefore, state codes 71 through 99 are not to be assigned by regulatory agencies in the United States for any public use.

Reserved Sidetrack Codes

The sidetrack codes 70-89 are reserved for proprietary use by companies and data systems. Therefore, these sidetrack codes are not assigned by regulatory agencies for any public use. These codes are reserved to answer a very special occasional need to identify dual data that can exist in a well, such as dual mechanical logs, cuttings, samples, cores, tests, shows, etc. This normally occurs as the result of a junked section of a hole. For example: 42-107-12345-70 would identify the dual data from the junked section; 42-107- 12345-00 (or 42-107-12345) identifies all of the data in the open hole of the weli fzm surface to total depth.

Supplemental Well Operations

Supplemen al well operations, such as recompletion, rework, d ning, repairs, etc., will be identified and controlled by an operations sequence coding procedure developed and maintained by the cooperative systems, not by state agencies. These supplemental well operations will be tied to the applicable API Well Number by these systems for data correlations. There will be no adjustment in the API Well Number itself to reflect or differentiate these operations.

In those instances where a regulatory agency issues permits for supplemental operations (such as deepening operations), it would be advantageous if that agency would record the API Well Number on the supplemental operations permit. This correlation by the agencies would be made as a service to the industry and made a matter of public record either within their offices or in published reports of supplemental operations made by the agency.

This can be accomplished for supplemental operations in states where the operator requesting the permit includes the API Well Number on the request. It is suggested that all operators include the API Well Number on their requests to regulatory agencies for supplemental operations permits.

ORIGIN OF STATE AND COUNTY NUMERIC CODES

Numeric Codes

State two-digit numeric codes--For the complete list of names and codes for the states of the United States and codes for the pseudo-states, refer to Section V, pp. 30-32 or Section VI, p. 64. Codes for the Canadian provinces, districts, and offshore areas are found in Section V, p. 52 or Section VI, p. 65.

County three-digit numeric codes--For the complete list of county names and codes for onshore states, including pseudo-county codes in offshore state waters, refer to Section VII, pp. 67-113.

Pseudo-counties offshore federal waters--For the complete list of names and codes for the pseudo-counties in offshore federal waters of Alaska, Paci- fie Coast, Northern Gulf of Mexico, and Atlantic Coast, refer to Section VIII, pp. 116-127.

Mexico--onshore and offshore codes--For the complete list of names and codes for the states of Mexico and the pseudo-states and pseudo-counties in offshore Mexican waters, refer to Section IX, pp. 128-133.

Origin of Codes for Onshore Wells

Onshore States--The numeric codes for the states were published as early as 1952 by IBM. States, including District of Columbia, were arranged alphabetically- then numbered -sequentially 1-49. After acquiring statehood, Alaska and Hawaii were added to the list as 50 and 51, respectively.

Onshore Counties--The onshore codes were assigned initially by arranging the county names alphabetically then sequentially assigning odd numbers. The even numbers are available in the event additional counties are created in a state. Since 1952, only two of the states' lists have been changed as a result of the creation of new counties, independent cities, or other similar add5tions. For the State of Alaska, the USGS quadrangle system has been adopted as pseudo-counties for use in making the DI Well Number assignments. Refer to the individual states for lists of the county names and numeric codes appropriate to each state in Section VII, pp. 67-113.

-24- 1/1/79 BULL DLZA-77 ---I0732290 0005207 B

Origin of Codes for Offshore Wells

The code structure for wells drilled in offshore marine waters presented a special problem because various codes had been devised in the past by non- related industry groups to meet their own needs. This complexity has been compounded with time by the progressive extension of activity further seaward, Additional problems are created when attempting to define the shoreline boundary of some states, the offshore boundaries between states, the offshore state-federal boundaries, and the subdivision of federal waters into pseudo- counties.

The APT recommended practice for assigning API Well Numbers to offshore wells is much the same as for onshore wells.

Wells drilled in marine state waters immediately offshore to the state carry the two-digit state code of that particular state. The sea areas adjacent to the shoreline, when divided into designated geographic offshore areas, are assigned three-digit area codes equivalent to a county code and used in the county code position of the API Well Number. Off- shore area codes for pseudo-counties of a state do not duplicate any onshore county codes for that state. The five-digit well code is assigned serially within each offshore area and the two-digit directional sidetrack subcode is assigned serially as a two-digit suffix in the same manner as for onshore wells.

Wells drilled in federal waters offshore are assigned pseudo-state codes, pseudo-county codes, then unique well codes in the same manner as onshore wells.

Methods of referencing and coding offshore areas vary for different areas. Descriptive details, explanations, and maps of the subdivision of state and federal offshore waters are found in Section V, pp. 30-57.

Offshore Marine State Waters

The procedures for coding wells drilled in offshore marine state waters differ considerably with the different geographical areas of the United States. For illustrations and additional discussion of these procedures, refer to the explanations associated with the maps illustrating individual geographic areas in Section V, pp. 30-57.

No attempt is made by API to identify the legal offshore boundaries between states. Where these boundaries are shown on the map, they are for illustrative purposes only.

-25- 1/1/79 BULL D12A-77 I0732270 0005208 O 1

Three-mile limit for state waters--Offshore marine state water bottoms extend seaward for three geographical (nautical) miles for all marine shoreline states with the exception of Texas and Florida. Texas offshore state water bottoms extend seaward for three marine leagues (nine nautical miles). Also, Florida offshore state waters in the Gulf of Mexico extend seaward for three marine leagues; on the Atlantic coast, Florida state waters extend seaward for three nautical miles.

Alaska--Wells drilled in offshore marine state waters will be coded with the state code 50 and the appropriate Alaskan USGS quadrangle pseudo-county code. This code number is obtained by adding +600 to the adjacent onshore quadrangle (pseudo-county) code (refer to pp. 34-37).

Pacific Coast States--California, Oregon, and Washington--All pseudo- county codes for marine state waters are numbered in the 200 series; the last two digits are identical to the last two digits of the code for the adjacent onshore county (refer to pp. 38-43).

To identify the California offshore islands, the pseudo-county codes are even numbers from 116-130. For state waters surrounding these islands use the corresponding 200 series, 216-230 (refer to pp. 40-41).

Texas--A 600 series and a 700 series of area codes have been used since 1968 to identify the offshore Bureau of Land Management mapped areas adjacent to the Texas coast. The 600 series refers to the Texas marine state water small tracts; the 700 series refers to the larger tracts seaward of the 600 series. The Texas state code 42 with the appropriate area code in the 600 or 700 series and with the 30000 series well code identifies current wells drilled in offshore Texas waters (refer to pp. 44-45).

Louisiana--The 700 series of codes has been used since 1968 to identify the offshore Bureau of Land Management mapped areas adjacent to the Louisiana coast. The Louisiana state code 17 with the appropriate 700 series code and with the 20000 series well code identifies current wells drilled in Louisiana waters (refer to pp. 46-47).

Gulf Coast State Waters--Alabama, Mississippi, and Florida--All pseudo- county codes for marine state waters of Alabama, Mississippi, and Florida are obtained by adding +200 to the adjacent onshore county code.

Atlantic Coast State Waters--Florida to Maine--All pseudo-county codes for marine state waters of Florida, South Carolina, North Carolina, Virginia, Maryland, Delaware, New Jersey, New York, Connecticut, Rhode Island, Massachu- setts, New Hampshire, and Maine are obtained by adding +200 to the adjacent onshore county code. Georgia is the one exception along the Atlantic Coast because of the large number of counties; in order to provide unique codes, add +300 to the adjacent onshore county code.

Offshore Federal Waters

The procedures for coding wells drilled in offshore federal waters differ with the different geographical areas of the continental United States. For illustrations and additional discussions of these procedures, refer to the explanations associated with the maps illustrating individual geographic areas in Section V, pp. 30-57.

No attempt is made by API to identify the legal offshore federal boundaries, especially the international boundaries. Where these boundaries are shown on the map, they are for illustrative purposes only.

California--Coding for wells in the Channel Islands Area remains as state code 04, area code (pseudo-counties) 300 series, and unique well code. Refer to pages 40 and 69.

Louisiana and Texas--Coding for wells drilled in offshore federal waters in the areas identified by the 700 series of codes remains the same. The 700 area codes identify Bureau of Land Management mapped areas. For Louisiana, use state code 17, appropriate 700 area code, and unique well code. Refer to pages 46 and 81. For Texas, use state code 42, appropriate 700 area code, and unique well code. Refer to pages 44 and 104.

In December 1970, the United States Geological Survey began assigning the 40000 series unique well codes in API Well Numbers to identify wells drilled in Federal Waters offshore to Louisiana and Texas.

Pseudo-state Codes for Offshore Federal Waters

The remaining federal waters bordering the continental United States are defined in the following four pseudo-states: Alaska, Pacific Coast, Northern Gulf of Mexico, and Atlantic Coast. Refer to Map 2, page 33 for the continental map illustrating these four areas.

Numeric two-digit codes for pseudo-states have been developed for U.S. offshore waters and for Mexico onshore and Mexico offshore waters as follows:

Code Number Geographic Name

55 Alaska Offshore Federal Waters of U.S. 56 Pacific Coast Offshore Federal Waters of U.S. 57 Mexico--Offshore Pacific Coast Mexican Waters 58 Mexico--Onshore States Mexico 59 Mexico--Offshore Gulf of Mexico and Caribbean Mexican Waters 60 Northern Gulf of Mexico Offshore Federal Waters of U.S. 61 Atlantic Coast Offshore Federal Waters of U.S.

Pseudo-county Codes For Offshore Federal Waters

In 1974, a procedure was recommended by the API Subcommittee on Well Data Retrieval Systems to define offshore pseudo-counties in federal waters as equivalent to those areas covered by Bureau of Land Management Outer Conti- nental Shelf (OCS) protraction diagrams (referred to as BLM maps) in the Northern Gulf of Mexico.

-27- 1/1/79 BULL D32A-79 10732290 0005230 t! 1

South of latitude 50" north, these BLM maps cover areas that are bounded by approximately 1" latitude and 2" longitude; and north of the 50" latitude, these BLM maps cover areas bounded by approximately 1" latitude and 3" longitude, Since the outer boundaries of these maps closely approximate lines of latitude and longitude, on a small scale regional map, the grid for the Uni- versal Transverse Mercator (UTM) quads (1" X 2' or 1" X 3") pictorially repre- sents the BLMmaps.

This plan is recommended for all offshore areas of the continental United States, For the purpose of clarifying the discussion in the text that follows, the following three terms describing areas are essentially synonyms:

1. Pseudo-county 2. BLM OCS Protraction Diagram (BLM map) 3, UTM quad (i" X 2" or 1" X 3")

Along the marine coastline, when the BLM map encompasses both land and sea areas, only the seaward portion in federal waters is considered as the federal pseudo-county.

System For Numbering Pseudo-Counties

Several schemes for numbering the UTM quads as pseudo-counties were considered before selection of this recommended system. Most of the proposals were for numbering systems already in use by oil and gas companies for their offshore data systems. All systems proposed were arbitrary, but each provided unique numbers for the pseudo-counties.

The system recommended by this Subcommittee appears to be the most logical and consistent of the ones considered. This system also has additional poten- tial benefits in that it provides the capability for making certain validity checks on latitude-longitude location of a well versus the assigned pseudo- county code.

The three new pseudo-states for the offshore areas of Alaska, Pacific Coast, and Atlantic Coast are subdivided into pseudo-counties equivalent to the BLM maps. Pseudo-county numbers are assigned beginning at O01 in the southeastmost UTM quad of each pseudo-state, then increased incrementally by +1 in columns from south to north, Thus, each pseudo-state is identified by an "origin point", which is the southeastmost latitude and longitude, and further identified by an upper limiting latitude, "top latitude". Each column of pseudo-counties is numbered sequentially from south to north; these columns extend as far westward as required.

Complete lists of the pseudo-county codes for offshore federal waters are found in Section VIII, pp. 116-127.

These UTM quads and their assigned pseudo-county numbers should never be used for assigning API Well Numbers when the well is located onshore or in state waters. The numbers used in this numbering system are continued across existing continental land areas, e.g., refer to Alaska., The numbers occuring over state land or state offshore waters are -not used for API Well Number assignment; use the appropriate state numbers for these areas.

ALASKA

Alaska Onshore--The State of Alaska is not subdivided into counties, The state's political subdivision is by election districts. Since these political boundaries are subject to change every ten years, a more stable division is required for well data systems. The USGS quadrangle system has been adopted as county equivalents for use in making the API Well Number assignments. These quadrangles were assigned three-digit codes and have been used to identify approximately 1,000 wells since 1968. These codes will continue to be used to identify onshore state lands and offshore state waters.

Alaska Marine State Waters--Alaskan offshore state waters extend seaward for three geographic (nautical) miles. This three-mile band parallels the marine shoreline and also surrounds the major offshore islands. Refer to Map No. 3 on facing page 35. Wells drilled in offshore state waters are coded with the state code 50 and the appropriate Alaskan USGS quadrangle (pseudo- county) code obtained by adding +600 to the onshore quadrangle number.

Federal Waters--Alaska Offshore--Pseudo-state Code 55

The offshore of Alaska is illustrated by two maps. Map No, 4, page 36 is a detailed map of the offshore federal waters of Alaska that shows the pseudo- county codes, UTM quad identity numbers, and BLM map names assigned to date. Map No. 5, page 37, is the same map but only the code numbers for the pseudo- counties are posted.

Offshore federal waters are defined as those marine waters occurring beyond the offshore three-mile geographic (nautical) limit for state waters. This line is normally indicated on all issues of the Bureau of Land Management OCS Protraction Diagrams.

The size of the UTM quads in these latitudes is 1" by 3". The pseudo- county numbers start with 001 at the southeast origin point (latitude 50' north, longitude 129" west) and the pseudo-county numbers are incremented in a north direction by +1 to the north bounding latitude 80'. The pseudo-county numbering extends westward by columns numbered south to north. The UTM quads cover the entire offshore waters of Alaska including all seas adjacent to the state coast. These UTM quads and their assigned numbers should never be used in assigning API Well Numbers when the well is located on state land or in state waters.

Federal water bottoms inside the USGS quadrangles (onshore pseudo- counties) will be numbered by the recommended offshore codes for federal waters, Any well located in federal waters offshore to Alaska should be assigned the pseudo-state code of 55, plus the new pseudo-county code.

Refer to Section VIII, pp. 116-127, for the detailed lists for each pseudo- county giving county numbers, the UTM quad identity numbers and the names that BLM has assigned to date.

Pseudo-state Code 56

The offshore area for the Pacific Coast--California, Oregon, and Washing- ton is illustrated by Map No. 8 on facing page 43. This map shows pseudo- county codes, corresponding UTM quad identity numbers, and BLM map names assigned to date to these areas. The size of the UTM quads in these latitudes is 1' by 2'. The pseudo- county numbers start with O01 at the southeast origin point (latitude 30' north, longitude 116' west), The pseudo-county numbers increment in a north direction by +1 to the north bounding latitude 50'. The pseudo-county numbering extends westward by columns numbered south to north.

Detailed listing of each pseudo-county, giving county number, the UTM quad identity number, and the map name assigned to date are found in Section VIII, pp. 122-123.

Approximately 300 wells have been drilled offshore in both state and federal waters of California, Oregon, and Washington to date, therefore, a conflict in identification numbers can occur. Refer to the previous discussion on state waters, pp. 40-41 of this section. Wells previously numbered in the Channel Islands Area will not be changed. These are the wells located within the Bureau of Land Management OCS Leasing Maps of California--sheets 6A, 6B, 6C, 6D, and 6E, and identified by area codes of 311, 312, and 313 as shown by Map No. 8 on facing page 43. The coding for wells in this area remains state code 04, area code (pseudo-county) 300 series, and unique well code. Codes established prior to this revision for the federal offshore waters outside the Channel Islands Area have been changed, Thirty-three wells in the Pacific offshore have been renumbered to conform to the new offshore area code designations, Offshore to California 21 wells were renumbered, 9 wells offshore to Oregon were renumbered, and 3 wells offshore to Washington were renumbered. The new well identification numbers, plus the old numbers, can be obtained from either the United States Geological Survey office that handles the appropriate offshore area, or from the scouting organizations or well data systems that maintain well files of the Pacific Coast wells.

TEXAS OFFSHORE

The offshore area for Texas marine state waters and adjacent federal waters is illustrated by Map No. 9 on facing page 45. For the purpose of separating wells drilled onshore Texas from wells drilled offshore, an arbitrary Tobin Data Process Line is used--this line is essentially the marine shoreline. All wells seaward from this line are classified offshore and offshore area codes are assigned as illustrated. All wells inland from this line are assigned onshore codes for the counties in which they are located. Exact location of this Process Line and the location of the offshore area boundary lines may be obtained from Tobin Research, Inc., San Antonio, Texas.

The offshore boundary between state and federal waters is stated to be three marine leagues (nine nautical miles).

A 600 series and a 700 series of codes have been used to identify the offshore Bureau of Land Management mapped areas. The 600 series, 600-606, are for the smaller water-bottom tracts and the 700 series, 700-715, are for the larger water-bottom tracts. Current wells drilled in these mapped areas are identified by Texas state code 42 with the appropriate 600 or 700 series code and with the 30000 series well code. For complete listing of these codes refer to the Texas county code list in Section VII, p. 104.

The United States Geological Survey assigns the API Well Number to wells drilled in federal waters. The 40000 series well codes are used currently to identify these wells in federal waters.

Federal waters seaward of the earlier series of BLM maps are described as Northern Gulf of Mexico, pseudo-state 60, refer to Map No. 11, page 49.

Pseudo-state Code 60

The offshore area for the Northern Gulf of Mexico, Texas to Florida, is illustrated by Map No. 11, on facing page 49. The map shows the pseudo-county codes, corresponding UTM quad identity numbers, and BLMmap names assigned to date.

This pseudo-state and its pseudo-counties were recommended by API for use by the industry in September 1974 as Supplement 1 to API BULLETIN D12A. The size of the UTM quads in these latitudes is 1' x 2O. The pseudo-county numbers were assigned as the 800 series, to separate them from the adjacent 700 series of pseudo-counties. The numbers are assigned north to south in columns; they start in the west along the Texas coast and increase eastward.

Detailed listing of each pseudo-county, giving county number, UTM quad identity number, and the map name assigned to date is found in Section VIII, pp. 124-125. -Note: Most of the names for the BLM Protraction Diagrams have been changed by the Bureau of Land Management since the 1974 publication of Supplement 1 to API BULLETIN D12A. The API pseudo-county numeric codes for these areas have not changed.

Note: To date, the Canadian oil and gas industry is not using the API Well Number concept to identify their wells on a unified country-wide basis. Instead, a numbering scheme based on land surveys, township-range-section, and quarters is used on a local basis, by provinces or portions of provinces.

NUMERIC CODES FOR MEXICO

Petroleos Mexicanos has assigned unique control numbers to all of the 12,000-13,000 wells in Mexico. This five-digit number is not organized geo- graphically, by states or areas, but is assigned on a country-wide basis,

When this control number is combined with a two-digit country code for Mexico, and a three-digit code for each state in Mexico, the wells can be then identified by a control number that is identical in format to the API Well Number.

In the interest of developing a numbering system compatible with wells drilled in the United States and in Canada, codes for Mexico are recommended for identifying the wells. This identity number will aid in the exchange of files of computer well data between Mexico and the United States.

All petroleum drilling activity, current and historical, is segregated by these codes into three separate major areas, each of which is assigned a two-digit number code: Mexico-Pacific Offshore, code 57; Mexico Onshore, code 58; Mexico-Gulf of Mexico and Caribbean Sea Offshore, code 59.

Onshore Mexico, Code 58

The states of Mexico are illustrated on Map 14 on facing page 55,. The states are arranged alphabetically then sequentially assigned three-digit codes. Each well drilled is assigned its own unique five-digit well code number. With the combination of country code, state code, and unique well code, the standard API Well Number is obtained, e.g,, a well drilled in the State of Chiapas would be identified by a ten-digit well number of 58-007- xxxxx . Offshore Mexico, Codes 57 and 59

The area offshore to Mexico for the Pacific Coast is illustrated on Map 15, page 56.

The area offshore to Mexico for the Gulf of Mexico and Caribbean Sea is illustrated on Map 16, page 57.

These two offshore areas are subdivided into sub-areas (as pseudo- counties) using the Universal Transverse Mecator (UTM) quads which are 1' x 2' in size. Each UTM quad is assigned its own unique three-digit code in the two areas.

Refer to the two maps pages 56 and 57 for the relative position of these sub-areas, and refer to Section IX,pp. 128-133,for complete lists of these UTM quads and their codes.

STANDARD NAMES AND NUMERIC CODES--FEDERAL GOVERNMENT

In August 1978, the National Bureau of Standards (NBS) published codes for more than 136,000 localities within the U.S. These codes implement volun- tary industry standard (ANS X3.47-1977) of the American National Standards Institute (ANSI) and have been developed for use by federal agencies, state and local governments, industry, and the public. The standard provides names and numeric codes for states, counties, cities, towns, and places such as urban townships, airports, and Indian reservations.

These names and codes may be obtained in book form (NBS-FIPS-55), in magnetic tape form (PB 247-150), and in microfiche form, 34 COM fiche 48:l reduction ratio (PB 274-146).

Ref: Federal Information Processing Standards Publication (NBS-FIPS -55), CODES FOR NAMED POPULATED PLACES AND RELATED ENTITIES OF THE STATES OF THE UNITED STATES, obtained from the National Technical Informa- tion Service (NTIS), U. S. Department of Commerce, Springfield, Virginia 22161,

Also, the General Services Administration, another agency of the Federal Government, has maintained and published for some time a de facto standard which provides numeric codes for geographic locations covering states, counties, and cities in the United States; outlying areas of the United States and cities. This publication also included continents, foreign countries, and foreign cities.

Ref: Federal Government Publication, WORLDWIDE GEOGRAPHIC LOCATION CODES, prepared by General Services Administration, Office of Finance, December 1976, S/N 022-000-00130-2, for sale at federal book out- lets, or Superintendent of Documents, U.S. Government Printing Office, Washington, D. C. 20402.

Both publications contain the same (identical) codes for the states and counties, However, an incompatibility exists between the state codes recommended in this publication (BULLETIN D12A) and those in the above-referenced government publications. The petroleum industry has been using the API recommended codes since 1962. Over one million wells are stored in computer data bases with these API state and county codes and innumerable computer applications are operational using these codes. These same files of well data are also used by the United States Geological Survey. To convert these files for the entire industry is virtually impossible and extremely costly. There- fore, API continues to recommend that the oil and gas industry use the established API BULLETIN D12A numeric codes for the states and counties.

A cursory examination of county codes also indicates that the government codes are not identical with those published in BULLETIN D12A. For Alaska, the referenced government publications use election districts as counties (or Bureau of Census districts), whereas BULLETIN D12A uses USGS quadrangles as pseudo-count ies . Finally, the government publications do not include any numeric codes to identify state marine water bottoms and federal water bottoms offshore for the states of Alaska, the Pacific Coast states, Gulf Coast states, and Atlantic Coast states.

** Current name is Cold Bay, USGS officially renamed Ft. Randall Quadrangle as Cold Bay Quadrangle. The State of Alaska does not have counties which can be used for the assignment of API Well Numbers. Areas identified by USGS quadrangles are used as pseudo-counties Three-digit codes assigned to these quadrangles are analagous to the normal "county code". Offshore locations in state waters inside-the quadrangle areas are identified by adding t600 to the adjacent onshore quadrangle code. NOTE: For offshore federal waters seaward of Alaska State waters, refer to ALASKA OFFSHORE FEDERAL WATERS, Map 4, page 36, or Map 5, page 37,in SECTION V, and list of codes,pages 118-121,in SECTION VIII.

OFFSHORE FEDERAL WATERS--NORTHERN GULF OF MEXICO

Note:- The pseudo-counties in the offshore federal waters in the three pseudo- states of Alaska, Pacific Coast, and Atlantic Coast and the pseudo- counties in offshore Mexican waters in the two pseudo-states of Mexico - Pacific Coast offshore and Mexico - Gulf of Mexico and Caribbean Sea offshore are all numbered by the same system, i.e., start with 001 in the southeastmost pseudo-county, increment by +1 in columns from south to north, and numbers increase to the west. The northern Gulf of Mexico, however, is an exception that does not follow this numbering system. First, the pseudo-county numbers are in the 800 series; second the numbers increment by +1 in columns from north to south, and numbers increase to the east.

UNDESIGNATED WATERS

Codes are needed occasionally to identify wells in undesignated state or federal waters outside existing mapped areas. The general codes in this section are for this purpose. Some of the earlier published undesignated waters codes are being replaced by new codes in this revised BULLETIN D12A (1-1-79) as a result of the establishment of offshore pseudo-states in Alaska, Pacific, and Atlantic marine waters.

-135- 1/1/79 BULL DL2A-77 10732270 0005338 b I*. --__-_-SUMMARY Where does one obtain API Well Numbers? Obtaining API Well Numbers for current wells generally presents little problem; also to obtain numbers for several historical wells is not too diffi- cult. However, obtaining -all numbers assigned to date in a state, or selected county(s), or selected area(s), requires some effort. A further complication--in many states all historic wells have not been assigned numbers to date. These are assigned as they are added to the data systems . Sources For API Well Numbers--Current Wells Operator--in most states the API Well Number is assigned at the time the well is issued the "permit to drill." This number is usually placed on the official permit and returned to the operator. Regulatory Agency-- for each state refer to the contact paragraph in Section VI1 for availability of numbers. Offshore Federal Waters--the appropriate United States Geological Survey office has files of these-numbers, refer to Section VIII, p. 117.
