Cicero, Andrea D. 20221216 tabular digital data https://www.sciencebase.gov U.S. Geological Survey https://doi.org/10.5066/P9KQU1XK This data release is an updated compilation of published and unpublished thermal maturity and source rock geochemical data (RockEval, pyrolysis) from subsurface wells and outcrops in the Permian Basin, west Texas and southeast New Mexico. This version clarifies the dispersed organic matter group for thermal maturity measurements, adds new data, references, and updates subsurface unit names. The dataset was created for the Energy Resources Program’s (ERP) National and Global Assessment of Oil and Gas Assessment (NAGA) project, which documents technically recoverable conventional and unconventional (continuous) oil and gas resources in priority basins in the US and abroad. These data record spatial and temporal variations in thermal maturity and source rock geochemistry of petroleum-bearing units in the Permian Basin of west Texas and southeast New Mexico. Typically these types of data are obtained and analyzed by petroleum industry operators and results are kept confidential. This updated data release (version 2.0) clarifies the dispersed organic matter group for thermal maturity measurements, adds new data, references, and updates subsurface unit names. This data release remains the largest public repository of source rock geochemistry and thermal maturity data for the Permian Basin Province since 2005. Subsurface unit and formation names determined by the author and approved by USGS Geologic Names committee. This data release consists of two files, geochemical data and detailed references of the source. 1983 2025 publication date Complete As needed -107.1359 -100.0388 33.4265 28.6468 USGS Thesaurus thermal maturity pyrolysis petroleum resources (gas) petroleum resources (oil) conventional continuous USGS Metadata Identifier USGS:625ebc43d34e85fa62b7f780 Geographic Names Information System (GNIS) Texas New Mexico Permian Basin Delaware Basin Midland Basin Central Basin Platform Val Verde Basin none none Andrea D.

Data were also collated from publicly available sources, such as theses and dissertations, state agencies, databases, as well as from the body of published literature. Areas with scarce or missing data were then identified. 2021 Andrea D Cicero U.S. Geological Survey, ROCKY MOUNTAIN REGION mailing address

Denver CO 80225 US 303-236-2392 acicero@usgs.gov Appropriate cuttings samples were identified from online databases listing holdings of the individual State core repositories. Samples were identified from the Integrated Core and Log Database (http://igor.beg.utexas.edu/crc2/) of the Texas Bureau of Economic Geology. 2021 New drill cuttings samples were collected by the author from 11 wells between February and May 2021 at the Bureau of Economic Geology's Houston Research Center (https://www.beg.utexas.edu/about/facilities/houston-research-center). Samples were split and sent to the USGS Petroleum Geochemistry Research Lab in Denver, Colorado and USGS Thermal Maturity Lab in Reston, Virginia. 2021 Total organic carbon (TOC) content was measured by analysts with the Petroleum Geochemistry Research Laboratory (PGRL) using a LECO C744 Carbon analyzer after carbonate removal with 6 M hydrochloric acid (Oliver and Warden, 2020). Programmed pyrolysis was performed using a Hydrocarbon Analyzer with Kinetics (HAWK, Wildcat Technologies, Dreier and Warden, 2021). Calculated parameters from HAWK data were determined by the PGRL laboratory using unrounded input values. Both TOC and HAWK analyses were performed according to the instrument manufacturers’ instructions, and internal laboratory check standards were run for quality assurance purposes.

Lakewood CO 80225 303-236-9375 jwycech@usgs.gov Samples were prepared for petrographic analysis according to ASTM D2797 (ASTM, 2015a). Samples were imaged under oil immersion on a Leica DM 4000 microscope equipped with LED illumination and monochrome camera detection (QMS identities Hilgers1 and Hilgers2) in white and blue incident light. Reflectance analyses were conducted according to ASTM D7708 (ASTM, 2015b) using the computer program DISKUS-FOSSIL by Hilgers Technisches Buero with a YAG calibration standard (0.908% Ro) from Klein and Becker. Petrographic evaluation indicates contamination in some samples, e.g., organic mud additives, migrated oil, metal shavings.

Digital and/or raster logs were obtained for most wells (S&P Global ® , TGS R360™, Texas Railroad Commission, New Mexico Oil Conservation Division, and University Lands). Informal subsurface units were assigned to each sample by the author. For wells without logs, subsurface units were extrapolated from nearby wells and author-generated structure maps and grids.
