Large areas of offshore Texas remain unexplored even though sedimentary facies and structural traps favor the generation and accumulation of hydrocarbons.

One nonconventional target for increased oil recovery in Texas is oil that remains in abandoned reservoirs, defined as reservoirs that produced no oil or gas in 1977 and 1982.

Bedded salt of the Permian San Andres Formation, Palo Duro Basin, Texas, is under consideration for the isolation of high-level nuclear waste.

Data collected during the last 5 years on the 15 shallow salt diapirs that extend upward to shallow depths (<4,000 ft, 1,220 m) in the East Texas Basin are presented here in graphical and tabular form.

The Edwards Formation, on the downthrown side of Mt. Bonnell fault in the Austin, Texas, area (Hays and Travis Counties), is part of the northeastern extension of the Edwards Underground Reservoir, the primary source of water in numerous counties along the Balcones Fault Zone.

Gas reservoirs that water out under moderate to strong water drives are normally abandoned when the expenses associated with salt-water disposal make continued operations uneconomical.

This report summarizes results of the East Texas Waste Isolation (ETWI) program from January 1, 1978, to March 30, 1983. Having an extensive data base, the study comprised 33 different lines of research by 67 scientists and research assistants.

Characterization of 500 of the largest Texas oil reservoirs permits grouping into plays of similar geology and common engineering and production attributes.
