Although the mature, supergiant East Texas field on the west flank of the Sabine Uplift has been producing from the Upper Cretaceous (Cenomanian) siliciclastic Woodbine Group for more than 75 years, no modern comprehensive geologic study of it has been completed.

Lineament analysis was used to study the relationship between subsurface structure and surficial features in East Texas, southeastern Oklahoma, southwestern Arkansas, and northwestern Louisiana-areas of low topographic relief, moderate vegetation cover, and diverse land use.

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.

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.

Correct interpretation of the effect of basin infilling on salt mobilization is critical to understanding salt dome growth and stability. The size of salt structures in the East Texas Basin is determined by the original thickness of the underlying Louann Salt (Middle Jurassic).

Post-Aptian strata (younger than 112 ma) in the East Texas Basin were strongly influenced by halokinesis and recorded the evolution associated sate structures.

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.

Principal fault systems in the East Texas Basin were examined in terms of their distribution, geometry, displacement history, and possible origins.
