Compaction and Cement Volume Analyses of the Lower Wilcox Sandstone Along the Texas Gulf Coast

Abstract

The Lower Wilcox strata are proven to be a good quality reservoir along the Central Gulf Coast of Texas. However, the complexity of its sedimentary environment makes it hard to accurately locate the isolated productive sand. In this study, rock physics analyses are carried out to provide a better understanding of the reservoir properties. Bulk density, P-wave velocity, and elastic moduli are extracted from four wells for analyzing the depth and temperature effects on compaction. A combination of three effective medium models is used for cement volume diagnostics.
