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.

Surface fissures have been observed in many desert basins in the western United States. These surface-collapse features are usually discovered after a normally dry surface has been covered with water, either by runoff from intense rainfall, by flooding, or by irrigation.

Regional and local hydrologic investigations were conducted in Trans-Pecos Texas as part of a study to evaluate potential sites for a low-level radioactive waste repository.

The Atlas of Major Central and Eastern Gulf Coast Gas Reservoirs is the second in a series compiling geologic and engineering data on natural gas reservoirs in the major gas-producing regions of the United States.

The 37-Ma-old Infiernito caldera of the northern Chinati Mountains is a major eruptive center of the mid-Tertiary volcanic field of Trans-Pecos Texas. Volcanism in the Chinati Mountains began with eruption of a sequence of rhyolitic to trachytic lavas, the precollapse lavas.

Chemical and physical approaches are used to study unsaturated flow; however, few studies include an in-depth analysis of data from both approaches.
