  • Towards Integrated Oil and Gas Databases in Iraq
    Towards Integrated Oil and Gas Databases in Iraq Dr. Zaid Haba Senior Information Technology Consultant December 2012 Introduction The oil and gas industry has to deal with huge amount of data throughout the lifecycle of the exploration, drilling, logging, production, refining, transportation, distribution and marketing of crude oil and gas, and has a voracious appetite for data. Exploration and Production (E&P) departments acquire Tera (1012) Bytes of seismic data which is processed to produce new projects, creating exponential growth of information. Furthermore, this data is increasingly acquired in 3 or 4 dimensions, creating some of the most challenging archiving and backup data management scenarios of any industry. The international oil industry has traditionally been at the forefront in the utilization of state-of-the art information technology tools for all aspects of its processes and operations, to manage the manipulation, storage and access of this data. This data covers: • Surveys data • Geological maps • Seismic data • Drilling and completion data • Wells data including logs • Reservoirs data • Production information • Infrastructure information • Crude oil analysis data • Leases This paper focuses on the vital importance of establishing and maintaining integrated oil databases for the oil industry in Iraq covering upstream activities. Much of the oil and gas data presently exist in various formats such as paper, maps, computer tapes, photographs, and computer disk files. These data are seriously under threat due to the age of some documents, maps, photographs and even electronic records, and the fact that much of the data are scattered in various locations so they are difficult to access centrally and by different technical roles in the E&P organizations.

  • Ar2011 02 Briefing Papers for Web.Indd
    ALASKA DIVISION OF GEOLOGICAL & GEOPHYSICAL SURVEYS FY12 Project Description DIGITAL GEOLOGIC DATABASE PROJECT In 2000, the Alaska Division of Geological & Geophysical Surveys (DGGS) saw an urgent need to develop a geologic database system to provide the architecture for consistent data input and organization. That database system now includes data identifica- tion and retrieval functions that guide and encourage users to access geologic data online. This project was initiated as part of the federally funded Minerals Data and Information Rescue in Alaska (MDIRA) program; ongoing data input, use, and maintenance of the database system are now an integral part of DGGS’s operations supported by State General Funds. DGGS’s digital geologic database (Geologic & Earth Resources Information Library of Alaska [GERILA]) has three primary objec- tives: (1) Maintain this spatially referenced geologic database system in a centralized data and information architecture with access to new DGGS geologic data; (2) create a functional, map-based, on-line system that allows the public to find and identify the type and geographic locations of geologic data available from DGGS and then retrieve and view or download the selected data along with national-standard metadata (http://www.dggs .alaska .gov/pubs/); and (3) integrate DGGS data with data from other, related geoscience agencies through the multi-agency web portal, http://akgeology.info. During the first 11 years, the project work group established a secure and stable enterprise database structure, started loading data into the database, and created multiple Web-based user interfaces. As a result, the public can access Alaska-related reports and maps published by DGGS, the U.S.

  • Databases to Support Gis/Rs Analyses of Earth Systems for Civil Society
    DESIGN AND IMPLEMENTATION OF “FACTUAL” DATABASES TO SUPPORT GIS/RS ANALYSES OF EARTH SYSTEMS FOR CIVIL SOCIETY Tsehaie Woldai * , Ernst Schetselaar Department of Earth Systems Analysis (ESA), International Institute for Geo-information Science and Earth Observation (ITC), P.O. Box 6, 7500 AA, Hengelosestraat 99, ENSCHEDE, The Netherlands, [email protected] , [email protected] KEY WORDS: ‘factual’ databases, field data capture, geographic information systems, geoscience, multidisciplinary surface categorizations, remote sensing ABSTRACT: With the increasing access to various types of remotely sensed and ancillary spatial data, there is a growing demand for an independent source of reliable ground data to systematically support information extraction for gaining an understanding of earth systems. Conventionally maps, ad-hoc sample campaigns or exclusively remotely sensed data are used but these approaches are not well suited for effective data integration. This paper discusses avenues towards alternative methods for field data acquisition geared to the extraction of information from remotely sensed and ancillary spatial datasets from a geoscience perspective. We foresee that the merging of expertise in recently developed mobile technology, database design and thematic geoscientific knowledge, provides the potential to deliver innovative strategies for the acquisition and analysis of ground data that could profoundly alter the methods how we model earth systems today. With further development and maturation of such research methodologies we ultimately envisage a situation where planners and researchers can with the same ease as they nowadays download remotely sensed data over the web, download standardized and reliable ‘factual’ datasets from the surface of the earth to process downloaded remotely sensed data for effective extraction of information.

The power of a GIS comes from its ability to look at entities in their geographical context and examine relationships between entities. thus a GIS database is much more than a collection of objects and attributes. in this unit we look at the ways a spatial database can be assembled from simple objects. For e.g. how are lines linked together to form complex hydrologic or transportation networks. For e.g. how can points, lines or areas be used to represent more complex entities like surfaces? POINT DATA 1. the simplest type of spatial object 2. choice of entities which will be represented as points depends on the scale of the map/study 3. e.g. on a large scale map - encode building structures as point locations 4. e.g. on a small scale map - encode cities as point locations 5. the coordinates of each point can be stored as two additional attributes 6. information on a set of points can be viewed as an extended attribute table each row is a point - all information about the point is contained in the row each column is an attribute two of the columns are the coordinates overhead - Point data here northing and easting represent y and x coordinates each point is independent of every other point, represented as a separate row in the database model LINE DATA Infrastructure networks transportation networks - highways and railroads utility networks - gas, electric, telephone, water airline networks - hubs and routes canals SABA KHANAM E-mail id: [email protected] , Contact no.

  • Geologic Resource Evaluation Scoping Summary for Marsh
    Geologic Resource Evaluation Scoping Summary Marsh-Billings-Rockefeller National Historical Park & Saint-Gaudens National Historic Site Geologic Resources Division National Park Service The Geologic Resource Evaluation (GRE) Program provides each of 270 identified natural area National Park Service (NPS) units with a geologic scoping meeting, a digital geologic map, and a geologic resource evaluation report. Geologic scoping meetings generate an evaluation of the adequacy of existing geologic maps for resource management, provide an opportunity for discussion of park-specific geologic management issues and, if possible, include a site visit with local geologic experts. The purpose of these meetings is to identify geologic mapping coverage and needs, distinctive geologic processes and features, resource management issues, and potential monitoring and research needs. Outcomes of this scoping process are a scoping summary (this report), a digital geologic map, and a geologic resource evaluation report. The National Park Service held a GRE scoping meeting for Marsh-Billings-Rockefeller National Historical Park (MABI) and Saint-Gaudens National Historic Site (SAGA) on July 10, 2007 at the University of Massachusetts, Amherst. Tim Connors (NPS-GRD) facilitated the discussion of map coverage and Bruce Heise (NPS-GRD) led the discussion regarding geologic processes and features at the two units. Participants at the meeting included NPS staff from the parks, Northeast Temperate Network, and Geologic Resources Division, geologists from the University

Any use of trade, product, or firm names in this publication is for descriptive purposes only and does not imply endorsement by the U.S. Government or State governments. FOREWORD If American citizens want a balanced and acceptable quality of life that is economi­ cally and environmentally secure, the states and the nation must provide a reliable geo­ logic-map foundation for decision-making and public policy. In this time of government downsizing, the state geological surveys and the U.S. Geological Survey are confronting a severe geologic- mapping crisis. Less than twenty percent of the United States is ade­ quately covered by geologic maps that are detailed and accurate enough for today's deci­ sions. Critical ground-water, fossil- fuel, mineral-resource, and environmental issues require accurate and up-to-date geologic information almost always in the form of maps to arrive at viable solutions. There are hundreds of examples of the important role geologic mapping plays in our society. In 1988, the Association of American State Geologists (AASG) and the United States Geological Survey (USGS) began to draft legislation that would require and fund a major, cooperative, nationwide geologic-mapping program to be administered by the USGS.
