United States Gulf Coast Basin Curated Wells and Logs Database (ver. 4.0, September 2025)

The United States (US) Gulf Coast Basin Curated Wells and Logs Database (CWLDB) is an online repository with stratigraphic information for petroleum wells in the United States portion of the onshore US Gulf Coast Basin that provides several of the following attributes: a) deep penetrations (generally, total depth of 10,000 feet or more), b) high quality and diverse geophysical well log suites, c) lithostratigraphic logs, d) biostratigraphic units (biozones) and reports, and/or e) core or cuttings samples.
