Published by U.S. Geological Survey | Department of the Interior | Metadata Last Checked: January 27, 2026 | Last Modified: 2024-05-15T00:00:00Z
This data release is a compilation of a literature search of published core X-ray diffraction (XRD) data for the Permian Basin Barnett and Woodford Shales, and includes data from: the Reliance Triple Crown 1 (RTC 1) well of Pecos County, Texas; Fasken Fee BM SWD 1 well of Andrews County, Texas; the M G Nevill well of Culberson County, Texas; the Mesquite 1 well of Hamilton County, Texas; the Fasken Fee BK 1514 well of Ector County, Texas; and Ross Draw Unit 5 well of Eddy County, New Mexico. The compiled data help advance the understanding of the stratigraphy, mineralogy, geomechanical properties, and depositional environment of these continuous hydrocarbon reservoirs in both the Midland Basin and Delaware Basin. The XRD data include but are not limited to weight percent (wt%) of albite, apatite, calcite, chlorite, dolomite, feldspar, illite, kaolinite, magnesite, mica, norsethite, orthoclase, plagioclase, pyrite, quartz, siderite, smectite, and total organic carbon (TOC).
