An integrated study using 3D seismic, wireline logs, and core analyses was conducted to establish new strategies for exploring compartmentalized, lowstand, prograding deltaic systems.

The Hueco Basin of Trans-Pecos Texas, which formed in response to Cenozoic extensional tectonism, lies within the southern Rio Grande rift near the poorly defined boundary between the rift and the southern Basin and Range province.

The Sabine Arch is a large (1 2,000 mi2 [31,000 km2]), low-amplitude anticline centered on the Texas-Louisiana border.

These cross sections illustrate the regional structure and stratigraphy beneath the Texas continental shelf .

The Palo Duro Basin of the Texas Panhandle and eastern New Mexico contains bedded Permian salts of sufficient thickness and depth for the basin to be considered as a potential site for long-term storage and isolation of high-level nuclear waste.

These cross sections numerically correspond to previously published onshore cross sections (CS0002--Dodge and Posey, 1981) and extend those sections across the continental shelf into the Miocene, a recent target of renewed petroleum exploration.
