Edwards-Trinity (Plateau) Aquifer 2D Seismic Study

Project Summary:

The objectives are to 1) identify seismic lines that may resolve the Edwards-Trinity formations in the study area and 2) lease select seismic lines to contribute to the structural understanding of the Aquifer.

Benefits:

Stakeholders have access to a report which includes reprocessed seismic lines that demonstrate the quality of seismic that may be obtained for shallow aquifers, and which show the structural characteristics of the Edwards-Trinity (Plateau) Aquifer in Kinney County. The report includes a feasability analysis of existing seismic lines over the Edwards-Trinity (Plateau) Aquifer for use in a brackish aquifer study, and the steps of how to reprocess and depth convert 2D seismic data. The report also describes the workflow for integrating outcrop, well, and seismic data into a comprehensive analysis of the aquifer.
