|Granite Wash, Palo Duro Basin, Texas
We found no thickness map of the entire evaporite aquitard that overlies the Granite Wash. However, adding the gridded isopach maps of the San Andres / Blaine Formations and the genetic unit above them results in thicknesses that approach or exceed 2,000 ft, ample seal thickness. (c7granitewash).
