14. Effects of Hinge Line Deposition and Truncation in the Anadarko Basin, Oklahoma [Abstract]

Richard D. Ash, Robert Klinger

Hydrocarbon accumulation along the northeast flank of the Anadarko Basin, Oklahoma, is found in stratigraphic traps formed by (1) truncation and (2) deposition, adjacent to the hinge line of the basin.

Production from the Mississippian Chester formation

indicates a relationship between hydrocarbon accumulation and the truncation of porous limestone units within the formation. Possible productive trends can be projected by determining which units of the Chester are penetrated below the Pre-Pennsylvanian unconformity.

Morrow sandstone hydrocarbon accumulation is found in a series of "shingel type" sands deposited as the transgressing Morrow seas crossed the area. The best potential stratigraphic traps were deposited basinward from the hinge line. Here, the sandstones are generally thicker, more abundant and pinch out more abruptly than those encountered on the shelf.

The study area presents an excellent potential for future exploration. In addition to Morrow and Chester production, there are at least 5 younger and older zones which produce hydrocarbons from stratigraphic traps.
