Braden Holt, OilPrice
Horizontal drilling and fracturing have been the keys which have unlocked vast oil reserves in North Dakota’s Bakken Shale and Texas’s Eagle Ford Shale. The success companies have achieved while developing those two formations has led to the search for other shale formations with similar geological characteristics. Enter stage left: the Tuscaloosa Marine Shale (TMS) which is a similar geological age to the Eagle Ford Shale. The formation is deep, with depths ranging from 11,000’ to 15,000’, but contains plus 90% oil cuts and is prospective for economic quantities of oil in Louisiana and Mississippi (see map below). Depths combined with low permeability in the TMS had previously dissuaded companies from developing the formation, but new technologies have led companies like...
