Abstract: Petrophysical Characterization of the Trinity Aquifer in North Texas

COLLIER, HUGHBERT, LYNN SMITH, and MICHAEL MCCRACKEN

The Cretaceous Trinity Group is the most extensive and prolific aquifer in North Texas, supplying both domestic and municipal water needs. In order to better quantify the hydrophysical properties of the aquifer, selected test holes have been cored and logged with an extensive suite of lithology and porosity logs. Permeability has been calculated from both pump tests and Stoneley wave analysis. Preliminary results of this study will be presented.
