Paper: The Relation of Geology to Fluid Injection in Permian Carbonate Reservoirs in West Texas

Fluid injection into the Permian carbonate rocks of West Texas has generated millions of barrels of additional reserves in recent years. Sufficient performance history is now available so that certain general conclusions may be drawn and guidelines set for future project installation. The fundamental precept for evaluating these reservoirs for fluid injection is a detailed knowledge of their geology. Permian carbonante reservoirs can be characterized by the dominant trapping mechanism into three distinct types. Different performance histories may be anticipated for each type. Reasonable predictive procedures may also be developed.
