Summary

An extensive archive containing more than 10,000 historical (1918–2020) geophysical logs collected in conjunction with studies done by various entities and more than 2,000 additional donated well and geophysical logs are stored in hard-copy at the Central Texas Branch of the Oklahoma-Texas Water Science Center (OTWSC) in Austin, Texas. This dataset addresses the need to preserve these records electronically by providing a scanned and indexed collection of 11,171 of these records. A scanned and indexed collection of the record are provided as comma-separated value (CSV) text file and a Microsoft Access database in ACCDB format containing detailed well header information for each record. Also included are zipped files containing the [...]

Purpose

This dataset was created to electronically preserve the historical well and geophysical log collection stored at the U.S. Geological Survey Oklahoma-Texas Water Science Center, and to enable online access of this resource by the public. The records can benefit both the scientific community and the public by providing online access to detailed data on hydrogeologic conditions in wells distributed across 141 Texas counties. Prior to the publication of this data, in-person use of the physical well log records by the public was being handled on a case-by-case basis. Electronic archives eliminate the risk of the original physical records being damaged, misplaced, or lost. This dataset addresses the need to preserve these records electronically.
