Disposal and temporary surface storage of spent geothermal fluids and surface subsidence and faulting are the major environmental problems that could arise from geopressured geothermal water production.

Sequential shoreline monitoring, using vintage chans and aerial photographs, documents temporal and spatial variations in historical Gulf shoreline changes.

Secondary leached porosity is common to dominant in near surface to deep subsurface lower Tertiary sandstone reservoirs along the Texas Gulf Coast. This secondary porosity is in the form of leached feldspar grains, volcanic rock fragments, carbonate cements, and carbonate-replaced grains.

Changes in the position and stability of shorelines around Corpus Christi, Oso, and Nueces Bays, Texas Gulf Coast, were documented using historical-monitoring techniques.

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 l

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.

The Gas Research Institute, U.S. Department of Energy, and the State of Texas cooperated in joint-venture research to evaluate the infield reserve growth potential of mature gas fields containing conventional reservoirs.

Shorelines bordering the bays of Texas are generally not as dynamic as those along the Gulf of Mexico. Nevertheless, the predominantly erosional movement of these bay shorelines translates to large losses of wetlands, arable uplands, and recreational and residential property.
