On November 19-21, 1985, members of WMGT staff and their technical assistance contractors met with DOE and their contractors at the Parke University Motel in Columbus, Ohio to discuss the geologic structure of the Palo Duro Basin, Texas. The purpose of the meeting was to examine the existing data that serves as the basis for interpretations of structural features In the Palo Duro Basin as presented in DOE contractor reports. The emphasis of the meeting was to evaluate the structural configuration and tectonic history of the basin. Principle meeting objectives were to determine the availability of data for structural interpretations, the differences in published interpretations, the significance of these differing interpretations, and methods for resolving these differences. Enclosed are copies of the list of meeting attendees (Enclosure 1), the meeting agenda (Enclosure 2), the signed meeting summary (Enclosure 3), and copies of all presentation materials (Enclosure 4).

Observations

The NRC had the following observations:

1. A significant amount of data available for structural interpretations of the Palo Duro Basin consists of boring logs of oil exploration wells and seismic surveys conducted for oil exploration. As part of site screening activities of the entire basin, project specific seismic data were obtained utilizing acquisition parameters which emphasize resolution in the approximate 2000 to 6000 ft. depth range. As such, the inherent uncertainty and limitations of these data for detailed structural analysis are recognized particularly with respect to near-surface strata.

2. The nature and distribution of the seismic and boring data are such that some variations in interpretations are possible for both the data and the resultant structural features.

3. Some available seismic data and remote sensing imagery, such as landsat and aerial photographs, do not appear to have been fully utilized. Much seismic data are proprietary in nature, and when approached by DOE contractors, the oil companies have refused to release the data. Other seismic data are known by DOE to be available from brokers; however, the quality and usefulness of this data is not well known. DOE should consider evaluating the availability and usefulness of all seismic data to determine if they can be obtained and if they are worth obtaining to assist in structural interpretations. It should be recognized that NRC has defined procedures for dealing with proprietary data. DOE may also wish to consider obtaining and evaluating other available remote sensing data such as various types and scales of aerial photography and radar imagery. Summary of NRC/DOE Meeting Page 2

a. Development of a conceptual regional tectonic model(s) to evaluate various structural interpretations.

b. Evaluations of the possible effects of strike-slip faulting including both the ability to recognize such features and their effect on structural interpretations.

c. Evaluations of the role of the Matador Arch and Oldham Nose in the regional tectonic setting.

d. Evaluations of the relationship between fracture patterns observed in boreholes, outcrops, and remote sensing data including the limitations of the various methods in recognizing these features.

e. Modelling of gravity and magnetic data.

f. Evaluations of potential reactivation of structural features through geologic time including the upward change in structural expression such as progression from faulting to folding to fracturing which may be expected and variations in fracture density and orientations over areas of deep faults in comparison with unfaulted areas.

g. Providing more emphasis on evaluating the presence or absence of folds and their role in the tectonic history of the area.

h. Resolving difficulties in identifying basement.

i. Reevaluation of the boundaries and the resultant effect of the regional stress field between the approximately N 700 E maximum horizontal stress field of the mid continent to the approximately N-S stress field of the Rio Grande rift.

5. It appears that DOE's contractors have made significant progress in developing and implementing a viable QA program; however, NRC questions if traceability of information from study to study can yet be demonstrated. From the meeting presentations, it is NRC's impression that each study is providing some checks and documentation; however, there appears to be little to no effort to cross-check from one study to another. Examples that arose during the meeting include: criteria used to identify faults on seismic lines, criteria used to eliminate or modify faults presented in the published literature and subcontractor reports and criteria to select stratigraphic "picks" from borehole logs. DOE may wish to have its QA personnel consider this concern. Summary of NRC/DOE Meeting Page 3

6. When planning for seismic reflection surveys NRC believes that:

a. Expanded coverage with seismic refraction profiling may provide much useful information concerning lateral and vertical variations of velocity values. Such information could be useful for 1) drill hole location optimization, 2) geohydrology characterization, and 3) planning of seismic reflections lines and evaluation of shallow reflection anomalies.

b. Dual programs may be desirable in certain areas to provide both shallow and deep structural data.

c. Shallow (less than 2000 feet) surveys should he considered in selected areas where the Alibates Fm is known to be faulted.

7. DOE should consider the usefulness and applicability of electrical and electromagnetic surveys in resolving structural and geohydrologic concerns.

8. Based on the DOE presentations of general types of planned site characterization studies, it appears to the NRC that current planning is focusing on. developing site specific studies. It is not as apparent that the same attention has been given to also developing regional investigations important to understanding site performance. During future meetings in which proposed studies are discussed this subject needs additional clarification. This subject should be evaluated in light of the performance objectives of 10 CFR 60.

9. The NRC staff appreciates the effort of DOE in making available at this meeting the key personnel involved in the structural evaluation of the Palo Duro Basin. The knowledge and candor of the presenters helped assure the success of the meeting in accomplishing its objectives. The NRC staff wishes to thank all DOE participants for their effort.

The DOE had the following observations:

1. A common data base has been available to all SRP investigators for use in structural and stratigraphic interpretation; each study has utilized selected portions of the data base. The regional nature of the currently available borehole information and seismic surveys permit conflicting structural interpretations.

2. SRP recognizes a need to develop a uniform approach to evaluation and interpretation of geotechnical data (i.e., criteria for (1) picking formation "tops" from geophysical logs, (2) picking faults on Palo Duro seismic sections, (3) assigning geologic horizons to seismic data, and (4) "time to depth" conversions.) Summary of NRC/DOE Meeting Page 4

3. It is important to obtain seismic data optimized for both basement structure and shallow structures (repository horizon and above). These two needs lead to conflicting requirements for data acquisition parameters if a single seismic survey is to be used. Consideration should be given to separate surveys for deep and shallow data.

4. The exploration geophysics industry (particularly seismic), is needed by the program because of their expertise, capital equipment, and software. However, the industry's procedures and software are largely proprietary and do not fully comply with the program's general requirements for QA. Nor can the industry be expected to comply by revealing their proprietary programs. Some agreement between NRC and SRP is desirable before site characterization activities to identify the acceptable applications of industry data.

5. The uncertainty in structural maps should be explicitly stated rather than relying solely on the indicated distribution of data points to suggest areas of greater or lesser control.

6. DOE needs to resolve the level of detail needed in structural tectonic models necessary at different phases prior of pre-licensing studies. Specifically, the interpretation of structures within the tectonic framework and the evaluation of performance objectives must be related to uncertainties inherent in the model.

7. There is the need to clearly define the implications to site performance of tectonism during various geologic periods.

8. Site studies require integration to achieve consistent conceptual models of geology, structure, and hydrology (e.g., structural control of geomorphic processes and depositional patterns, and interrelationship of the geologic framework to hydrogeologic processes.

9. Available remote sensing data have not been utilized and completely eval uated.

10. This meeting demonstrates the desireability of early technical interchanges between DOE and NRC to discuss existing data and uncertainties in interpretations. Such discussions are valuable to expedite the later review of the SCP.

11. It was noted-that relatively little information exists concerning the Dockum Formation across the entire panhandle. Some approaches to enhancing our understanding of this unit include geological and structural mapping in areas of exposure (e.g., Canadian Piver Valley), and shallow reflection/refraction seismic surveys. SUMMARY OF NRC/DOE MEETING ON THE STRUCTURE AND TECTONICS OF THE PALO DURO BASIN

Observations The NRC had the following observations: 1. A significant amount of data available for structural interpretations of the Palo Duro Basin consists of boring logs of oil exploration wells and seismic surveys conducted for oil exploration. As part of site screening activities of the entire basin, project specific seismic data were obtained utilizing acquisition parameters which emphasize resolution in the approximate 2000 to 6000 ft. depth range. As such, the inherent uncertainty and limitations of these data for detailed structural analysis are recognized particularly with respect to near-surface strata. Response: DOE recognizes the inherent limitations of existing seismic data. The regional database was intended to provide a basis for screening large land areas to define preferred study sites for detailed characterization and as such, are reconnaissance in nature. As indicated in DOE Observation 3, it is important, during site characterization, to obtain seismic data optimized for both basement structure and shallow structures (repository horizon and above). These considerations are currently being addressed in the planning of site characterization seismic data acquisition. 2. The nature and distribution of-the seismic and boring data are such that some variations in interpretations are possible for both the data and the resultant structural features. Response: This point is raised as DOE's Observation 1. The issue of greatest importance is the impact of any reasonable alternative interpretation on expected site performance. Site Characterization studies of local and regional structural elements will be based on overall site performance considerations (to be discussed in the SCP), not on questions of strictly academic interest. It may well turn out that the differing interpretations of regional structure based upon screening data have no impact on demonstrated release rates (and probabilities) from the candidate site. 3. Some available seismic data and remote sensing imagery, such as landsat and aerial photographs, do not appear to have been fully utilized. Much seismic data are proprietary in nature, and when approached by DOE contractors, the oil companies have refused to release the data. Other seismic data are known by DOE to be available from brokers; however, the quality and usefulness of this data is not well known. DOE should consider evaluating the availability and usefulness of all seismic data to determine if they can be obtained and if they are worth obtaining to assist in structural interpretations. It should be recognized that NRC has defined procedures for dealing with proprietary data. DOE may also wish to consider obtaining and evaluating other available remote sensing data such as various types and scales of aerial photography and radar imagery. Summary of NRC/DOE Meeting Page 2

Response: a. Available Seismic Data - DOE has obtained representative, good quality seismic data of the site and region. It is recognized that additional brokered data exists and is desirable, particularly north of the site and over the Amarillo uplift. Further significant data at the site do not seem available through open channels with oil companies. Also, much of the available data is not of a quality (resolution at depths of interest) to be very useful to the program. Regarding seismic data owned by oil and gas exploration firms, it may be possible, on a case by case basis, to examine either the raw data or interpretations, but it is unclear how these proprietary lines can be used in an open, public program. DOE will continue to pursue this matter with NRC staff. b. Remote Sensing Imagery - Some investigation of both satellite imagery and aerial photography of the Palo Duro Basin region has already occurred. The site has been flown at a detailed scale to permit construction of topographic maps for engineering design. DOE has recently received a subcontractor evaluation of landsat imagery of the Palo Duro region, and is performing a technical review of this study. As a result of this review, it is anticipated that additional remote sensing imagery analyses can be recommended which will be of use to the Salt Repository Project. A recent flyover was made of the Deaf Smith site using Side-Looking Airborne Radar (SLAR). This imagery, when available, will be evaluted to further utilize remote sensing within the Salt Repository Project.

4. In the development of their site characterization plans DOE should consider developing a comprehensive integration of the available data. The following data elements have been addressed to some degree; however, NRC considers the integration effort should include: a. Development of a conceptual regional tectonic model(s) to evaluate various structural interpretations. b. Evaluations of the possible effects of strick-slip faulting including both the ability to recognize such features and their effect on structural interpretations. c. Evaluations of the role of the Matador Arch and Oldham Nose in the regional tectonic setting. -d. Evaluations of the relationship between fracture patterns observed in boreholes, outcrops, and remote sensing data including the limitations of the various methods in recognizing these features. e. Modelling of gravity and magnetic data. f. Evaluations of potential reactivation of structural features through geologic time including the upward change in structural expression such as progression from faulting to folding to fracturing which may be expected and variations in fracture density and orientations over areas of deep faults in comparison with unfaulted areas. Summary of NRC/DOE Meeting Page 3

g. Providing more emphasis on evaluating the presence or absence of folds and their role in the tectonic history of the area. ' h. Resolving difficulties in identifying basement. i. Reevaluation of the boundaries and the resultant effect of the regional stress field between the approximately N 700 E maximum horizontal stress field of the mid continent to the approximately N-S stress field of the Rio Grande rift. Response: DOE agrees that it is desirable to provide an integrated geological analysis with the site description in the Chapters 1 through 4 of the Site Characterization Plan (SCP). The points raised in this observation will be considered to the extent possible in the SCP. 5. It appears that DOE's contractors have made significant progress in developing and implementing a viable QA program; however, NRC questions if traceability of information from study to study can yet be demonstrated. From the meeting presentations, it is NRC's impression that each study is providing some checks and documentation; however, there appears to be little to no effort to cross-check from one study to another. Examples that arose during the meeting include: criteria used to identify faults on seismic lines, criteria used to eliminate or modify faults presented in the published literature and subcontractor reports and criteria to select stratigraphic "picks" from borehole logs. DOE may wish to have its QA personnel consider this concern. Response: DOE has expended considerable effort over the past serveral years to develop a consistent and coordinated Quality Assurance (QA) program which meets the requirements of NQA-1 and 10 CFR 50, Appendix B. QA provides the means of documenting how an activity was conducted, i.e., the steps taken in each analysis leading to a specific interpretation. The key is to understand how varying the data reduction method changes the overall interpretation. It is recognized that as the program enters the site characterization phase to collect licensing information, it will be necessary to focus on a single approach to data interpretation (e.g., defined criteria for selecting formation tops from E-logs) by all contract research groups. Appropriate procedures will be developed for site characterization analytical work. However, some flexibility will still need to be provided to allow alternative approaches to be considered. 6. When planning for seismic surveys NRC believes that: a. Expanded coverage with seismic refraction profiling may provide much useful information concerning lateral and vertical variations of velocity values. Such information could be useful for 1) drill hole location optimization, 2) geohydrology characterization, and 3) planning of seismic reflections lines and evaluation of shallow reflection anomalies. Summary of NRC/DOE Meeting Page 4

b. Dual programs may be desirable in certain areas to provide both shallow and deep structural data. Nc. Shallow (less than 2000 feet) surveys should be considered in selected areas where the Alibates Fm is known to be faulted. Response: a. Cost-benefit considerations are a mandated part of the repository program. Both reflection and refraction programs are planned to address either specific issues or to provide needed support for other studies. (1) Lateral and vertical variations of seismic velocity are probably insufficient to have any influence on optimizing the siting of drill holes. Sites will be selected to optimize the intended purpose for each hole, such as stratigraphic or hydrologic studies. Limited seismic work will be used to indicate that anamolous conditions are not present. Targeting an anomaly would be an exception. (2) Hydrologists have indicated that the upper aquifer studies will require: elevations for the water table (available from existing water wells), the Ogallala-Dockum contact, and the base of the Dockum on about a 1/8-mile, or larger, grid. Variations in seismic velocity within the aquifer are not readily correlated with hydrologic parameters. The means to provide the desired data points will be considered in preparing the SCP. (3) The reflection work will desire datum statics from refraction arrivals as an integral part of the reflection program, or will use a specialized refraction program to address datum statics only. b. Agree with NRC. c. Agree with NRC. Plans and rationale will be provided in the SCP and subject to NRC review.

7. DOE should consider the usefulness and applicability of electrical and electromagnetic surveys in resolving structural and geohydrologic concerns. Response: The type of investigations to be conducted during site characterization will be matched to the issues to be resolved and overall site performance objectives. The SRP Issue Resolution Strategy, which will be presented in Section 8.2 of the SCP, will describe the type of information necessary to address questions of site performance. Associated field study plans will present the approach to collecting that information. All available geophysical survey techniques will be considered, as appropriate. Summary of NRC/DOE Meeting Page 5

8.i Based on the DOE presentations of general types of planned site character- tization studies, it appears to the NRC that current planning is focusing on developing site specific studies. It is not as apparent that the same attention has been given to also developing regional investigations important to understanding site performance. During future meetings in which proposed studies are discussed this subject needs additional clarification. This subject should be evaluated in light of the performance objectives of 10 CFR 60. Response: SRP agrees with the need to evaluate site performance within a regional geologic context. However, the necessary level of detail for regional understanding is not well defined at this time. The SCP for the candidate salt site will describe what is known of the regional geology and important alternative interpretations. Chapter 8 of the SCP will define site performance objectives, and list the issues to be resolved through site characterization studies in order to demonstrate a level of site performance. Additionally, Chapter 8 will present what is believed to be a reasonable set of activities, including regional studies, to assure issue resolution. We look forward to further inter- actions with the NRC on this subject to assure that all substantive concerns and recommendations are accomodated.

9. The NRC staff appreciates that effort of DOE in making available at this meeting the key personnel involved in the structural evaluation of the Palo Duro Basin. The knowledge and candor of the presentors helped assure the success of the meeting in accomplishing its objectives. The NRC staff wishes to thank all DOE participants for their effort. Response: SRPO concurs with the observation on the usefulness of this type of working meeting where all participants have an opportunity to discuss ideas in an open, professional environment. We would like to maintain this format for future discussions. &Waft 6)

Structural geology and tectonic history of the Palo Duro Basin and adjoining areas. 1. Introduction The structural geology and tectonic history of the Palo Duro Basin is closely related to that of the adjoining areas. Therefore, to fully understand the structural development of the Palo Duro Basin it has been necessary to examine the history of deformation of not only of the basin and adjoining areas, but the entire region as well. 11.Structural geology of areas marginal to the Palo Duro Basin. A. Amarillo Uplift -- a major positive structural element of the Ancestral Rocky Mountains: has been internally deformed into a series of horsts and grabens: B. Whittenburg Trough -- deep pull-apart graben along south side of Amarillo Uplift: C. Oldham-Harmon structural trend -- northwest-trending series of en echelon basement blocks that lie along the northern margin of the Palo Duro Basin: D. Matador Arch -- east-west trending series of en echelon basement blocks that separate the Palo Duro and Midland Basins: E. Roosevelt positive -- broad positive area that separates the Palo Duro and Tucumcari Basins. Ill. Structural geology of the Palo Duro Basin. A. The Palo Duro Basin is a structural low that occupies the southern part of the Texas Panhandle. It was a discrete depositional basin only during the Late Pennsylvanian. B. Deformation appears to decrease southward from the Oldham-Harmon trend: C. Structures within the basin are generally isolated positives and poorly defined lows: 1) Castro Trough -- northwest-trending low extending from Swisher County to Deaf Smith County; 2) Central Randall positive -- fault-bounded structure that probably typifies structures within the basin: 3) Deaf Smith County -- poor control, but there appear to be northwest- and northeast-trending faults. D. Dominent structural grain is northwest-southeast, although northeast-southwest trending structures are locally important. IV. Tectonic history of the Palo Duro Basin and surrounding region. A. Tectonic history of the basin was defined using structural and stratigraphic data: information for the surrounding areas came primarily from published sources. B. Deformation has been episodic: timing coincident with deformation of adjoining areas to east and west: 1. Proterozoic -- volcanism (1400 Ma). primarily rhyolite with related granite. similar rocks extend northeastward to Missouri. 2. Cambrian -- rifting associated with opening of the Southern Oklahoma Aulacogen. 3. Cambrian to Early Devonian -- carbonate shelf. 4. Middle Devonian -- folding of the Texas Arch and Anadarko Basin: formation of regional unconformity.

5. Mississippian -- carbonate shelf.

6. Pennsylvanian -- Ancestral Rocky Mountain orogeny, formation of Palo Duro depositional basin: 75 miles left-lateral strike-slip faulting along Amarillo Uplift. 7. Permian -- regional subsidence associated with formation of the Permian Basin. transition from normal marine to restricted depositional conditions during Early Permian. 8. Triassic -- non-marine deposition during subsidence that was possibly associated with rifting in Gulf of Mexico. 9. Cretaceous -- very shallow marine to non-marine environments. No evidence of Laramide deformation. 10. Tertiary -- reactivation of basement structures during deposition of the Ogallala Formation in Late Miocene, coincident with Basin and Range deformation to the west. 11. Quaternary -- tectonic activity along Amarillo-Wichita Uplift. as indicated by seismicity in Whittenburg Trough; movement along Meers Fault in Oklahoma. AWI- W -M

The RFP issued in June, 1982, requested bidders to provide price per mile quotations as follows: A. Recording 1. Spread: split/straddle using 24 phones (14 or 28 Hz dampened 60% of critical) per trace. 2. Vibrators: three available with not less than two operating to employ 20 (2 x 10) 7 second sweeps at 20 to 120 Hz input for 11 seconds. 3. Recording: 2 ms sample rate at 18-120 Hz band pass. Quote price per mile for each of the following configurations: a. 96 trace - 48 fold - 55' group interval - 55' sweep interval b. 96 trace - 24 fold - 55' group interval - 110' sweep interval c. 48 trace - 24 fold - 110' group interval - 110' sweep interval B. Processing 1. Specify and quote a processing sequence of operations utilizing state of the art production techniques at a 2 ms sample rate. 2. Provide full scale and half scale sections - three second length, full scale sections to be 20 traces per inch horizontally at 55' group and sweep intervals and 10" per second of reflection time vertically. Western Geophysical Company was the successful bidder. Field experimentation designed to establish recording parameters were conducted on July 7 and 8, 1982. C. The following Recording Parameters were selected: 1. Geophones: 16 per group - 10 Hz - dampened 70%c of critical; changed to 24 per group on April 6, 1983 2. Group length: 165' 3. Group interval: 55' 4. Spread: 2805' - 220' - 0 - 220' - 2805' 5. Source: Sweep frequency 17 to 85 Hz - 3 vibrators - 30 (3 x 10) 9 sec. sweeps 6. 13 sec. record length - 2 ms sample rate 7. Filter: 12 - 90 Hz - Notch 60 D. Processing Parameters were essentially as specified and quoted by WGC. These included: Edit/Demultiplex, correlation and vertical sum; digital filtering, datum statics and trace balance; zero phase deconvolution; CDP gathers; velocity analysis; automatic statics; Nt'10; coherency stack; gain and time variant filtering. A 3.0 second record length for processing was selected to minimize cost. Comparisons between 24 fold and 48 fold processing failed to justify the increased cost of 48 fold processing.

Reprocessing of Seismic Reflection Data I. Introduction Difficulty in interpretation of the DOE seismic reflection profiles collected in 1982 and 1983 prompted the reprocessing of the data by the Bureau and the University of Texas. Institute for Geophysics. Specific problems with the original stacked data included: 1. the discontinuous nature of the Alibates reflector, possibly as a result of salt dissolution; 2. the variation in strength of reflectors associated with the San Andres Formation along the profiles; and 3. the lack of good resolution of the basement surface. in part because the seismic acquistion parameters were set to maximize resolution at the level of the San Andres Formation. The three primary objectives of the reprocessing program were to: 1) study the near surface data to identify acquision and/or processing problems that may have affected the continuity of reflectors; 2) examine the data in the vicinity of the San Andres Formation to determine the nature of lateral variability in the reflectors: and 3) better delineate the location of the basement surface, if possible. with the available data.

II. Procedures A. Near surface reflectors were examined in a small-fold study of the field data using near traces. In addition. velocity studies were made to insure that the data were properly stacked. B. Complex attributes of the data (instanteous frequency and amplitude) were determined from the stacked data to more precisely identify events associated with the San Andres Formation and the basement surface. Ill. Conclusions A. In the cases studied. the disruption of near surface reflectors was related to loss of fold in the vicinity of "no permit" areas. Incorrect stacking velocities and the presence of a strong airwave also contributed to the lack of continuity. A study of each line would be necessary determine if all apparent disruptions are artifacts of acquision and/or processing techniques. B. Lateral variations in the San Andres Formation are. in part. related to variation in quality of data. and. in part. appear to be related to horizonal variations in bulk rock characteristics. However. there are insufficent geologic data at the present time to fully interpret the results. C. Although complex attributes differ for the basement and overlying sedimentary section. no unique seismic signature was noted for the basement surface. I

Agenda Joint NRC/SRP Workshop November 19-21, 1985, Parke University Hotel, Columbus, Ohio

STRUCTURE AND TECTONICS OF THE PALO DURO BASIN

Objective: Participants at this workshop will obtain an understanding of the current state of knowledge of the structural features of the Palo Duro Basin. The focus will be on evaluating the present structural configuration of the basin and its tectonic history and setting. Current seismicity and active tectonic processes in the region will not be discussed.

The data base from which structural interpretations have been made will be examined. The workshop will identify areas where contractor interpretations of existing data differ, and consider methods to resolve those differences.

Interpretation of seismic reflection data

1. Introduction Seismic reflection data were examined as an aid to structural and stratigraphic studies within the basin. All available stratigraphic and velocity data were integrated to interpret the seismic data. 11.Procedures used in the identification of reflectors: 1. Compared of synthetic seismograms and VSP data from DOE wells with adjacent seismic reflection profiles. 2. Constructed time/depth plots using check shot data from petroleum exploration wells. in areas without synthetic seismograms. 3. Used regional isopach and structural data as aid to interpreting basement reflector. 111. Problems 1. Acquisition parameters were inappropriate for resolving deep structure. 2. No-permit areas resulted in degraded data. 3. Problems with statics corrections and velocity determinations produced mis- ties with well data. 4. SWEC lines did not tie well to each other nor to lines from other surveys. 5. Poor velocity control reduced reliability of structure maps produced from seismic data. 6. Variablility in quality of data made it difficult to trace structures from line to line. IV. Conclusions 1. The available seismic reflection data have been useful for examining the gross structural continuity of Permian strata within the Palo Duro Basin. However. details of faulting are still unresolved. 2. The accuracy of structure contour maps developed from the seismic data is probably low because of poor velocity control. both regionally and along individual lines. 0 10 to MILEB

Qualitg Assurance Procedures for Data Collection/ Interpretation of Borehole Information

As we have seen there are a wide range of very useful data that are derived from the DOE boreholes. The reliability of the physical end chemical characteristics determined for each type of material rests on the validity of the processes used to analyze those materials. Even more important is the integrity of the samples from which thoses results were obtained. Therefore the Bureau places great importance on ensuring the quality of the samples that are to be analysed. Analytical results are no better than the samples from which those results were obtained. The integrity of the samples (in our case primarily well cores) is controlled by quality assurance procedures. The qu^/yali of the semples is the first concern of the data coillectonanf d interpretstion s stem These written documents describe in detail how cores and associated samples are identified, handled, sampled, and shipped. They are:

5. MSL 001: Methods for Collecting and Handling Samples for Macrochemical and Trace Chemical Analyses

6. QAP C 1.1.13: Procedures for Handling, Shipping and Storage The secondarea of control through our quality assurance procedures is in the interpretertation of the analytical data from the samples. The following procedures are relevent to the Bureau's interpretation of borehole derived data:

FRACTURE INVESTIGATIONS OF THE PALO DURO BASIN AREA

Eddie Collins. BEG

1. Regional fracture orientations -- figs. 2.3 - data collected in Permian and Triassic strata - data includes joint strikes measured in outcrop and fracture orientations measured from fracture identification logs - data for each one degree by one degree quadrant has been plotted together - have plotted general fracture orientations and fracture

orientations that are significant at a 95% confidence level - regionally, west-east striking fractures are signifcant in Permian strata Deaf Smith Co. also has NE striking fractures

2. Vertical and lateral continuity of fractures

2.1 Faults, folds. joints - figs. 4-6 - at western part of study area one signifcant joint set strikes NE. parallel to the strike of the Alamosa Creek and Bonita Faults - northeast of Deaf Smith Co.. joints were studied in Permian. Triassic and Tertiary rocks at a flexure off the southwest flank of John Ray Dome; at intervals along a traverse in the different age 1 strata, strikes of a representative joint from each set were measured: data has been plotted in azimuth vs traverse distance

plots and rose diagrams: data show a well defined NW striking

joint set in the overlying strata. parallel to the flexure axis: fracture spacing is closely spaced in Permian and Triassic sandstones (5-8 joints across 1 m in 1-2 m beds); Tertiary Ogallala strata also have a well defined NE striking joint set

2.2 Joint zones - fig. 7 - in relatively undeformed strata, zones of closely spaced joints extend vertically through Permian and Triassic strata: these joint zones range in width from 10 to 40 m and have been traced laterally up to I km

2.3 Joint spacing vs bed thickness - fig. 8

- the number of joints across two meters were measured for sandstone beds of different thicknesses: figure 8 shows plotted data

2.4 Lateral variability of joint orientations - figs. 9. 10

- strikes of vertical gypsum-filled joints in Permian strata were measured along three traverses at Palo Duro Canyon State Park: data are plotted in azimuth vs traverse distance plots and rose diagrams

- data show well defined E-W striking joints throughout the area; most of the joints strike NNW at the northern traverse (fig. 10): 2 the middle traverse (traverse 2) shows the strikes of the NNW oriented joints drift northwestward and NW striking joints become most common

3. Preliminary evaluations of fractures and veins in the core

3.1 General occurrance of fractures and veins - figs. 11-13

- core show that Permian strata are cut by gypsum. halite. anhydrite. and calcite veins, as well as fractures with no mineral filling: most of the fractures without mineral fillings are the result of drilling coring, however some are thought to be natural

- for this study the strata has been grouped into three categories based on lithology and stratigraphic sequence: the categories are

(1) strata below salt units. (2) strata that contain bedded halite. and (3) deformed strata above the salt units (salt dissolution zone)

- based on the core descriptions, the percentage of fractured core

for each category has been determined by dividing the number of one foot core intervals containing fractures by the total core footage

- data show that strata above the bedded halite units are more fractured than the salt zone units: the salt zone unit category contains the lowest percentages of fractured core: for strata below the bedded halite units, core from the Mansfield well located on the Bravo Dome has the greatest percentage of fractured core

3 3.2 Gypsum veins (core and outcrop) - figs. 14- 27 strata overlying salt units commonly have vein fillings of gypsum

- core and outcrop studies show gypsum veins are common in a deformed strata zone

- veins are composed of fibrous gypsum bisected by a medial scar; they are thought to be antitaxial crack-seal veins (Ramsay and Huber. 1983); the medial scar marks the site of earliest mineralization with new material added at the vein - wall rock contact: the mineral fibers indicate the direction of maximum principal extension at the time they were added to the vein

-gentle subsidence and collapse is thought to have opened the gypsum filled fractures

3.3 Halite veins - figs. 28-32

- fibrous halite veins fill fractures in bedded units

- veins occur within mudstone, siltstone. and carbonate interbeds

- some veins exhibit a subpolygonal pattern on bedding planes: these may have a desiccation or synaeresis related origin

- some veins exhibit a postcompactional origin: they are eliptical in shape and do not exclusively V' downwards; fracture filling is not zoned and contains no silt or mud filling: crosscutting relationships show that many veins postdate compaction and cementation

3.4 Veins and fractures below halite units - fig. 33 4 - calcite and anhydrite veins are present as well as fractures without mineral fillings

3.5 Fracture orientations in Deaf Smith Co. - fig. 34

- fracture orientations have been interpreted using fracture

identification logs; these logs have limitations: data show westward and northeastward fracture orientations

Generally, the older the log the poorer the quality. The oldest log in our data base dates from 1931. These older logs were resistivity and were types run in holes using poor drilling techniques, poor mud programs, and crude instruments which were not serviced regularly. Technological advances over the years have improved the quality of logs and their interpretation immensely. Quality also varies with each logging service.

The following compares the type of geophysical log vs. use.

Percentage of Used for file (est.) Correlation Lithology

Resistivity Logs (all forms) 40% Fair Poor Gamma Ray - Neutron (all forms) 25% Fair Poor Gamma Ray - Density (all forms) 15% Good Good Gamma Ray - Sonic (all forms) 15%' Good Good Neutron, Density, Sonic (no gamma- 1% Poor Poor ray) All logs 4% Excellent Excellent

All of the data is available for purchase from commercial sources listed earlier. All of the interpretations regarding formations, major salt beds, and porosity determinations are on computer tape.

E.) Organization

l) All information from each well are in folders arranged by state, alphabetically by county, and by number.

2) SWEC identification numbers match Bureau numbers up to July, 1980 Those numbers assigned to wells afterwards are followed by the letter "S" (not included in computer file). The original set of numbers were assigned from West to East and North to South. Later numbers were assigned to wells based on order of acquisition. Each county has numbers begining with No. 1. The county codes are listed on Attachment 2.

3) Each Folder contains:

- Geophysical Logs (if any) - Sample Logs (if any) - Mud Logs (if any) - State Records (if any) Applications to drill

Plats Completion Reports -3-

(used to check elevation, verify location, type and location of production and yields, driller's logs)

- Well Record Sheet Lists Formation tops and salt beds

4) Computer file

- Entered from well record sheet, salt information listed separately on Attachment 5, p. 2 - changes to file made on change sheets, stamped by originator, Project Geologist when checked, and when change is verified and transferred to master file.

- change sheets.organized by state, alphabetically by county, by number, chronologically.

5) Maps

- Postings of Formation tops or thicknesses with and/or without contours.

- Posting of elevations at a 1:250,000 scale and checked against 2 degree USGS Topographic Map.

- check of anomalous values for possible errors. -105-W'W-. -1lOJ-OO'W' -103'o-0o- -102-00'00' -lOil-W'W', -100-00'00' "WO' -- O ''-,'0

PALO DURO BASIN PROJECT INTERPRETATION OF SEISMIC DATA

1. VELOCITY DATA - Assemble, classify and integrate vertical velocity data with subsurface data. Reduce velocity data to a common reference datum. i i Determine reflection times for subsurface geologic markers at points of control. z 2. MAPPING HORIZONS - Identify and select the reflections/subsurface horizons to be mapped. (USA, LSAI, Wc and PreC) 3. SUBSURFACE REFLECTION TRAVERSES - Identify and mark the reflection horizons to be mapped on the seismic sections. Close all seismic subsurface traverses by adjusting to compensate for loop misclosures. Revise seismic time horizons as required to tie at points where velocity and electric log data are available. Time the seismic horizons at appropriate intervals and post the times to a base map. 4. STRUCTURAL CONFIGURATION - Contour time maps. 5. SECONDARY ADJUSTMENTS - Utilizing the horizon dip attitudes indicated by the time structure maps, project and tie the horizons to offline points of velocity/subsurface control making adjustments to the seismic horizons and contour maps as required. 6. APPARENT AVERAGE VELOCITY MAPS - Determine the apparent average velocity to each mapped horizon at each well within the survey from the contoured time value of the horizon at the well and the depth of the corresponding subsurface marker. Post these values to a base map and contour the apparent average velocity configuration for each mapped horizon. The I differences in apparent average velocity observed over the area repre- sent a combination of lateral changes in the vertical velocity gradient and unresolved near surface corrections. 7. TIME-DEPTH CONVERSION - For each mapped horizon compare the time map postings with the apparent average vertical velocity configuration, determine the average velocity at that station, and convert reflection times to depths. Post these values to the base map. Prepare isopach maps and depth maps for each horizon.

Figure 40. Facies and environments recorded in Tubb strata of the Palo Duro and Dalhart Basins. Evaporite-carbonate facies record a gradual basinward shift in environments. Siliciclastic (red-bed) facies dominate the Tubb sequence, and were deposited in tidal mud flats, which graded basinward into tidal sand flats. From Presley (1980b).
