The purposes of this study were (1) to quantify recent (1974 to 1982) movement of Texas shorelines and vegetation lines by analysis of aerial photographs; (2) to place this movement in historical (pre-1974) context; and (3) to examine the influence of environmental variables such as storms, sea level, subsidence, and sediment supply on the movem

Detailed characterization of the spatial distribution of hydraulic conductivity (K) by direct measurement is usually impractical. A viable alternative is to use geologic information and geostatistics to characterize interconnectedness of critical K facies that have a dominant influence on fluid flow.

In the western Delaware Basin and southern Central Basin Platform of Trans-Pecos Texas, Upper Permian (Ochoan) evaporite strata host locally voluminous but notoriously unpredictable, sporadic deposits of biogenic native sulfur.

Along the Texas Gulf shoreline and offshore, the distal margin of the Frio Formation is a deep hydrocarbon province that is underexplored relative to the onshore Frio.

Successful development of low-permeability-sandstone gas reservoirs depends on an understandingof their natural fracture patterns and on predictions of the orientation of horizontal stresses.This report describes the preliminary results of fracture analysis of the Lower Cretaceous TravisPeak Formation, a tabular sandstone and shale unit approxim
