This Report of Investigations describes a geological, petrophysical, and reservoir engineering study of the South Cowden field, Ector County, in West Texas. This product is the downloadable version. A geological, petrophysical, and reservoir engineering study was conducted of waterflood performance in the South Cowden field, an Upper Permian Grayburg reservoir on the Central Basin Platform in West Texas.

This report describes the three-dimensional distribution of hydraulic conductivity in the Edwards aquifer from Kinney to Comal Counties, Texas. Quantitative and interpretive assessment of the three-dimensional distribution of permeability in the prolific, complex, and heterogeneous Edwards fractured karstic aquifer leads to improved understanding of the dynamic behavior of the aquifer and identifies areas where information is lacking.
