DPA--Intro 5--The Proposal


	Introduction, Purpose, and Scope, continued The Proposal

The Northern Mid-continent Petroleum Atlas Consortium proposes to develop a digital and hard-copy atlas of petroleum in the northern mid-continent region. The atlas will encompass both oil and gas, will add to the TORIS data base, and will build on existing data sets and previous projects funded by USDOE. It is intended that the results will be immediately useful to operators in the region to add to reserves and producibility of existing fields.

The northern mid-continent region is geologically coherent comprising the southwestern-central part of the North American craton. Reservoirs in Kansas, Nebraska, South Dakota, North Dakota, the Williston basin portion of Montana, the Denver-Julesburg basin of eastern Colorado and southeastern Colorado are included in this region. These reservoirs formed mostly as epeiric sea deposits that overlapped the edge of the North American Precambrian shield. The region is typified by a profusion of combination traps, fewer structural traps, and stratigraphic traps. The original porosity and permeability of many reservoirs were modified by diagenesis associated with unconformities, subaerial exposure, or proximity to evaporites. Buried valleys and karst-process porosity development are abundant. Divergent origins of fields result in sets of plays defined by critical differences in reservoir systems.

Northern Mid-continent Petroleum Atlas Consortium

The Northern Mid-continent Petroleum Atlas Consortium is a working partnership of the state geological surveys of Kansas, Nebraska, South Dakota, and Colorado, the Colorado School of Mines, the University of Kansas Energy Research Center, Carroll Petroleum, Golden and Land Oil Company, and Harris, Brown, and Klemmer, Inc. Through the state surveys, graduate students and faculty of the University of Kansas and the University of Nebraska may become participants. Independents and consultants who are recognized geological and petroleum recovery experts are also participants in the consortium. The Northern Mid-continent Atlas Consortium, Kansas independents, and broad contacts within the independent industry agree that petroleum information in concise and organized format can materially assist the industry in exploration, development, and additional recovery efforts.
