Abstract

The Surface Casing Estimator Site is a website that provides estimates of possible surface-casing requirements for wells and related information. Work during FY12 for the Surface Casing Estimator Site project involved (1) scanning more than 11,250 geophysical logs of the Q-log library for 13 Texas counties, (2) constructing digital data sets composed of geologic information that relates to estimating surface-casing requirements for a four-county study area in east-central Texas and a three-county study area in south Texas, and (3) merging/programming the new data with the website's existing data. The Estimator Site provides information on elevations and depths for the top and base of fresh water, base of usable-quality water, base of the underground source of drinking water, top and base of critical water-bearing stratigraphic units, aquifer names, geophysical logs, and well locations. The FY12 work also has enabled about 880 additional geophysical logs to be viewed through the Surface Casing Estimator Site.
