Core Testing for Hill Country Trinity aquifer

Project Summary:

The objective is to conduct core testing, which involves using a core drill to obtain a sample of rock and sending it to a laboratory for direct measurement of properties using specific lab instruments. Core testing is the most direct possible way to define parameters of the rock and will provide the information for variables necessary to most accurately calculate total dissolved solids (TDS). Empirically deriving the bulk mineralogy, porosity, permeability, and cementation or “m”-factor for each formation of interest will yield more accurate TDS calculations. The combined use of these measurements will enhance the ability to accurately assess the brackish characteristics of formations of interest.
