Salt structures can be extremely challenging to interpret and understand. To begin with, the high velocity contrast between salt and most sedimentary rocks means that many salt structures are poorly imaged on seismic data.

This report describes a case history in a densely drilled, but spatially restricted, area (47 km2) containing 240 wells in the Mioceno Norte Area of Lake Maracaibo, Venezuela.

We examined the relationship between three data types--geologic maps, measurements of pavement deflection under load, and seismic refraction data-- from diverse geologic settings in Texas to determine (1) whether geologic maps and seismic refraction data might be used to interpret deflections and

Seismic interpreters must have a reliable methodology that allows them to (1) correlate seismic reflection events with well-log-defined sequence boundaries and (2) specify which seismic facies windows correspond to the rock facies intervals defined by well control.

This report presents three types of evidence documenting that the combination of P-wave and S-wave seismic data provides geologic insights that cannot be provided by conventional P-wave data alone.

Potential for commercial hydrocarbon accumulations in Eocene and older strata of the Duval County Ranch in South Texas was assessed using seismic data. Three seismic facies are recognized and tied to well control.

The origin of thousands of playa basins on the Southern High Plains of Texas and New Mexico has been attributed to eolian deflation, evaporite or carbonate dissolution and subsidence, piping, or animal activity.

Several microearthquake recording stations were operated as a network in the East Texas Basin beginning in June 1981. At least six certain and two probable earthquakes as well as hundreds of events of undetermined origin were recorded through August 1982.
