Project will develop a prototype for a digital and hard-copy atlas of petroleum fields and reservoirs in the northern Mid-continent region. A limited number of reservoirs in Kansas are to be included in the prototype project, but the goal is to expand beyond the prototype atlas to include significant reservoirs representing the major plays in Kansas, Nebraska, South Dakota, North Dakota, the Williston basin portion of Montana, the Denver-Julesburg basin of eastern Colorado and southeastern Colorado.

Primary products of the prototype atlas will be on-line accessible digital data bases covering two selected petroleum plays in Kansas. The regional databases will be supplemented with geological field studies of selected fields in each play. Digital imagery, digital mapping, relational data queries, and geographical information systems will be integral to the field studies and regional data sets. Data sets will have relational links to provide opportunity for history-matching, feasibility, and risk analysis tests on contemplated exploration and development projects. The flexible "web-like" design of the atlas provides ready access to data, and technology at a variety of scales from regional, to field, to lease, and finally to the individual bore. The digital structure of the atlas permits the operator to access comprehensive reservoir data and customize the interpretative products (e.g., maps and cross-sections) to their needs. The atlas will be accessible in digital form on-line and through CD-ROM using a World-Wide-Web browser as the graphical user interface.

Regional data sets and field studies will be free-standing entities that will be made available on-line through the Internet to users as they are completed. Technology transfer activities will commence in the early part of this project, providing data information sets to operators prior to the full digital atlas compilation.

Summary of Technical Progress

"Pages" and data schema for the atlas overview and field studies have been developed and are accessible through the world-wide-web. The atlas structure includes access to geologic, geophysical and production information at levels from the national, to the regional, to the field to the individual well. Several approaches have been developed that provide efficient and flexible screening and search procedures. The prototype of the digital atlas is accessible through the Kansas Geological Survey Petroleum Research Section (PRS) HomePage (The Universal Resource Locator [URL] is http://www.kgs.ku.edu/PRS/PRS.html). The Digital Petroleum Atlas (DPA) HomePage is available directly at http://www.kgs.ku.edu/DPA/dpaHome.html. Technology transfer is underway through the use of monthly electronic updates and the on-line availability of the DPA products. Project information and Quarterly Progress Reports are linked to the Digital Petroleum Atlas HomePage.

On-line Prototype

The prototype digital atlas is being designed, tested and constructed. At present the prototype covers Arroyo, Big Bow and Gentzler fields. The present prototype design consists of the following components:
DPA HomePage: http://www.kgs.ku.edu/DPA/dpaHome.html

The DPA Homepage has been expanded to include links to project information, such as progress and topical reports, and to discussions of plays, basins and geological provinces at both the national and Kansas levels. Much of the information at the national and province level is from the US Geological Survey 1995 National Assessment of United States Oil and Gas Resources (available on CD-ROM from the USGS as Digital Data Series DDS-30, Release 2). The USGS material will be supplemented with additional regional material covering the Kansas basins. Included in the discussion are maps of regions and geologic provinces, overview discussions, historical data and quick-time movies of the exploration history at national, province, basin, and play levels. All information is linked through graphical user interfaces. Examples can be found at

National Level: http://www.kgs.ku.edu/DPA/frontEnd/regions1.html
Province Level: http://www.kgs.ku.edu/DPA/frontEnd/Region/midcontinent.html
(Midcontinent Province)
Basin Level: http://www.kgs.ku.edu/DPA/frontEnd/Anadarko/anadarko.html
(Anadarko Basin)
Play Level: http://www.kgs.ku.edu/DPA/frontEnd/Anadarko/Morrow/morrow.html
(Morrow Play).

Also included on the DPA Homepage is an expandable listing of producing regions, basins and plays (http://www.kgs.ku.edu/DPA/frontEnd/Plays/regionList1.html). Clicking on the plus will provide links to more detailed information while clicking on the minus will show less detailed information about the selected region, province or play.

Access to the Kansas DPA Homepage is through the National DPA HomePage.
Kansas DPA HomePage: http://www.kgs.ku.edu/DPA/dpaKansas.html This page provides access to Kansas information and was the DPA HomePage in previous versions of the Atlas. Improved search routines for wells and fields have been added as four buttons at the top of the page.

Regional information (such as gravity and magnetic maps) has been generated for the four counties containing fields that are part of the atlas at this time (indicated by solid coloring). Clicking on the other counties will take you to annual oil and gas production files. In addition 30 counties provide access to oil and gas field maps (indicated by cross hatching).
Parameter Searches:

Fields and wells can now be searched by geographic location, name (API number or field name) and in the case of fields by a flexible search routine that incorporates production and geologic parameters. Searching fields by parameters can be accessed at [replaced by http://www.kgs.ku.edu/Magellan/Field/index.html]. As an example a search on all fields in Kansas discovered since 1985 that had cumulative oil production greater than 500,000 barrels returned the names and summary data for 24 fields. Arroyo and Big Bow fields are among the list and are returned as active links that can be used to access additional information.

County Maps:

Regional maps show the field outlines and provide access to selected geologic and geophysical maps. Click on the name of the field to go to pages about that field. Access through a GUI stratigraphic column to show structure or isopach maps. Four counties are complete and 30 additional counties provide access through oil and gas field outline maps.

Field Title Page:

Outline of producing leases; location of discovery well(s), condensed field statistics, and access to field production data. Additional information was added to all the fields covered by the Atlas. In addition, preliminary data has been added for the Gentzler Field in Stevens County.

Regional Setting:

The regional setting page provides a geologic and production perspective at a regional scale. Improvements include additional geologic and geophysical information covering Stanton, Grant, Stevens and Ness counties.

General Information:

Basic geologic, geophysical, fluid, engineering, completion, and production data at the field scale.

Geological Information:

Access to geologic field maps and cross-sections though a type log graphical user interface. Clicking on selected horizon provides access to multiple maps at different levels.

Geophysical Information:

At present, geophysical data for Arroyo Field in Stanton County is available.

Reservoir Information:

In the case of Arroyo Field this page contians access to petrophysical plots and to core descriptions http://www.kgs.ku.edu/DPA/Arroyo/Reservoir/arroyoRese1.html. The page will contain additional reservoir engineering and geologic information.

Well Information

Provides access to information on a single wellbore. Access is through an interactive map (click on the well symbol) and through a forms-based search. Data includes raster image of original completion report, digital "scout ticket" data, production data in graphical and digital formats, and digital log data. Prototype pages have been developed for presentation of core data (such as core photos, porosity and permeability data, descriptions, and thin-sections). Additional wells were added for Gentzler Field in Stevens County (http://www.kgs.ku.edu/DPA/Gentzler/gentzlerMain.html ).
All components are accessible through a standard suite of "buttons" that are at the bottom of every page.

Technology Transfer

The prototype Digital Petroleum Atlas continues to be one of the most visited pages on the Kansas Geological Survey web site (Current usage statistics can be accessed at the bottom of the Petroleum Research Section HomePage or at http://www.kgs.ku.edu/PRS/usage/past_stats.html). Usage has steadily increased to over 5,000 access "hits" per week (Figure 1). A presentation at the Society of Independent Petroleum Earth Scientists (SIPES) national convention in Dallas, and a booth at the national convention of the AAPG were well received. Presentations featuring the DPA are scheduled for the annual meeting of the Kansas Independent Oil and Gas Association (KIOGA) on August 26 and at an educational seminar for the Kansas Petroleum Council on September 18.
