Description

The Patoka Anticline, like the flanking Fairman Anticline, strikes northeast and displays closure at all mapped horizons from Galena (Trenton) Group (Ordovician) through Pennsylvanian. A Silurian reef occurs at the northeastern end of the Patoka Anticline. Compactional draping over the reef accentuates the anticlinal structure in post-Silurian strata. Smoot (1958) thought that the Patoka Anticline was initially developed in pre-Silurian time and provided a high spot on the sea floor favorable for formation of the reef. Nearly 15 million barrels of oil have been produced from lower Chesterian and upper Valmeyeran sandstones. Devonian and Galena (Trenton) limestone reservoirs also have been produced in the Patoka Oil Field.
