Regional Previous HitCrossNext Hit Section Program for Illinois Basin

Janis D. Treworgy, Stephen T. Whitaker

For the first time, the Illinois State Geological Survey will publish a network of regional Previous HitcrossNext Hit Previous HitsectionsNext Hit portraying the Previous HitstructuralNext Hit and stratigraphic framework of the entire Illinois basin. The network of 16 Previous HitstructuralNext Hit Previous HitcrossNext Hit Previous HitsectionsNext Hit radiating outward from the Union Oil 1 Cisne Community well (Sec. 3, T1N, 7E, Wayne County, Illinois) will consist of wireline logs showing formation boundaries and gross lithofacies of the entire stratigraphic column for over 140 wells. Indiana and Kentucky portions of the network will be prepared in conjunction with their respective state geological surveys.

Wireline logs are being digitized and stored to allow reproduction of log curves at different scales and in various combinations. Initial Previous HitcrossNext Hit Previous HitsectionsNext Hit will be published at a vertical scale of 1 in. = 400 ft and a horizontal scale of 1 in. = 8 mi (1:500,000).

To assure the most accurate Previous HitstructuralNext Hit and lithologic portrayals possible, numerous wireline logs are being examined in addition to the 140 illustrated on the Previous HitsectionsNext Hit. Available seismic data, sample and core descriptions, and existing structure, isopach, and facies Previous HitmapsNext Hit are also being used.

Text describing the Previous HitsectionsNext Hit will be included on each sheet. Topics will cover a brief history of deposition and Previous HitstructuralNext Hit evolution, distribution of source rocks, reservoir rocks and seals, and significant fields and plays.
