Title: More wells will expand knowledge of Knox group, Black Warrior basin

Abstract

The Arbuckle group of the Arkoma, Ardmore, and Anadarko basins was essentially untested in 1986. This paper reports that in these basins, shallower Pennsylvanian reservoirs were easy to reach and more economical to develop. The general consensus was that if a karstic reservoir was not present at the top of the Arbuckle group then there was no potential for oil and gas. Today the story is different; production zones are being found throughout the Arbuckle group, and drilling has been as deep as 28,000 ft. The Black Warrior basin is in a similar setting to the Arkoma, it is a foreland basin that has produced from multiple Mississippian and Pennsylvanian horizons at shallow depths. The Knox carbonate is present in a similar structural setting to that of the Arbuckle group at depths generally above 15,000 ft. In addition, Alabama is even more fortunate in that the buried Appalachian fold and thrust belt along the southern boundary of the basin also provides additional Knox targets with great promise. In this area Knox dolomites are fractured and folded and are juxtaposed by thrust faulting against Mississippian and Pennsylvanian rocks that are excellent sources of oil and gas. Therefore, the Knox is essentiallymore » untested in the Black Warrior basin.« less
