A dataset of scanned historical well and geophysical logs from 229 counties in Texas, 1918–2020 (ver. 2.1, September 2025)

An extensive archive containing more than 15,000 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 U.S. Geological Survey Oklahoma-Texas Water Science Center (OTWSC) in Austin, Texas. The dataset described herein addresses the need to preserve these records electronically by providing a scanned and indexed collection of 15,475 of these logs. Detailed well header information for each record is provided as both a comma-separated value (CSV) text file and a Microsoft Access database in ACCDB format. Also included are zipped files containing the geophysical-log scans in Portable Document Format (PDF). The original dataset was published in January 2024 with 6,058 log scans and an initial revision was made in September 2024, incorporating 5,113 additional log scans with header information into the original dataset. A final revision was made in September 2025 that incorporated an additional 4,304 log scans and header information in the dataset. The original logs scans and header information were not changed except for minor edits in response to quality assurance reviews .
