Kansas Geological Survey, Open File Report 97-14

Digital Petroleum Atlas Annual Report 1996

United States Regions and Geologic Provinces HomePage

United States Regions HomePage provides links to 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 (

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 U.S.G.S. as Digital Data Series DDS-30, Release 2). The U. S. G. S. material has been supplemented and in some cases replaced by regional and play material covering the Kansas basins. All regional information is linked through graphical user interfaces.

Northern Mid-continent Digital Petroleum Atlas HomePage

The Northern Mid-continent HomePage provides interactive maps and expanding lists that outline the region and its geologic provinces ( The long-term goal of the DPA project remains to expand beyond the prototype atlas in Kansas in order to include all significant reservoirs representing the major plays in the Northern Mid-continent (Figure 1a). The Northern Midcontinent as defined for the DPA includes all of Kansas, Nebraska, South Dakota, North Dakota, the Williston basin portion of Montana, and the Denver-Julesburg basin of eastern Colorado (Figure 1b). From the Northern Mid-continent HomePage one can access similar regional information as is found on the US Regions HomePage. Included on the Northern Mid-continent HomePage are links to

The system, sequence and play lists expand to provide more detail. As an example the Pennsylvanian, Lower Absaroka Sequence will provide access to a set of regional maps (paleogeography and accumulation rates) and a list of plays associated with this sequence throughout the region ( Selecting the Morrow Sandstone Gas and Oil Stratigraphic Play in the Anadarko Basin provides the regional detail on the this particular play with summary, estimate of resources, accumulation versus size graphs, etc. ( Detailed discussion is restricted to the Mississippian and Morrow plays of Kansas that were part of the one year prototype. However this architecture provides a methodology for covering similar plays across different basins and states.
