Summary
Groundwater-quality data and geophysical information for relatively deep wells (wells generally more than 300 feet deep) containing saline water (dissolved-solids concentrations greater than 2,000 milligrams per liter) are limited throughout the state of Texas. Information derived from geophysical well logs can be used to estimate groundwater salinity. Geophysical logs were collected in 2021 from 10 of the 12 wells completed in selected aquifers (Trinity, Edwards-Trinity (Plateau), Carrizo-Wilcox, Sparta, and Yegua-Jackson) in Texas.

Purpose
The purpose of this data release is to present the results of geophysical logs collected at 10 of the 12 total wells in selected aquifers (Trinity, Edwards-Trinity (Plateau), Carrizo-Wilcox, Sparta, and Yegua-Jackson) in Texas. The geophysical logs collected included a suite of conventional geophysical logs such as caliper, natural gamma, self-potential, induction resistivity, short-normal resistivity, long-normal resistivity, single-point resistance, lateral resistivity, fluid temperature, and fluid resistivity as well as an advanced geophysical log of either full-waveform sonic or nuclear magnetic resonance to estimate formation porosity. Resistivity and porosity information can be used to estimate groundwater salinity in locations lacking water-quality data.
