This dataset contains a global compillation of geothermal gradient estimates in boreholes from sedimentary basins all over the world. The data largely supports the analysis in the Geoscience Frontiers publication: Kolawole & Evenick (2023), Global distribution of geothermal gradients in sedimentary basins, doi.org/10.1016/j.gsf.2023.101685. An exception in the data is the proprietary data sourced from FrogTech SEEBASE reports (https://www.geognostics.com/frogtech-seebase-studies) that is not inlcuded in this release. Kolawole, F., Evenick, J.C. (2023). Global Distribution of Geothermal Gradients in Sedimentary Basins. Geoscience Frontiers, 14(6), p.101685. Doi: 10.1016/j.gsf.2023.101685. The here in attached zip folder contains:1. Global geothermal gradient database as described above, provided in .csv and .txt formats. Each data entry includes: Reference Number (same as in Data Sources file), API/UWI (where available), Longitude (Decimal Degrees), Latitude (Decimal Degrees), Region, Country, Well Name (where available), Geothermal Gradient (°C/km), Data Source.2. List of data sources and their references, provided in excel .xlsx format Acknowledgement:We thank the Exploration Technology Center (ETC) of BP Exploration, Houston, U.S. for supporting the implementation of this research project during the time F. Kolawole and J. C. Evenick worked there, the release of the public domain portion of the compilled geothermal gradient database, and for the permission to publish the database.
