This dataset contains estimated total organic carbon (TOC) calculated using the delta log R (dlogR) method, developed by Passey and others (1990), within BasinMod modeling software for the Tuscaloosa marine shale (TMS) in southwestern Mississippi, U.S.A. BasinMod is a modeling software developed by Platte River Associates, Inc. Using version 2021-03-03 of the software, sonic and resistivity logs and a background TOC of 0.8 weight percent were used to calculate dlogR TOC in the TMS high resistivity zone (HRZ) after baselining these two log curves in a non-source rock interval within the TMS. Due to variable mineralogy between the upper and lower sections of the TMS, two baselines were selected to determine whether...

This compilation presents total organic carbon and pyrolysis analysis data for the Pierre Shale, Niobrara Formation, and other Cretaceous marine shales in the Raton Basin-Sierra Grande Uplift Province. The data was used to characterize these potential source rock intervals in support of the oil and gas resource assessment in the province. The data was compiled from the publicly available files at the USGS Core Research Center in Lakewood, Colorado and from published literature.

In 2021 the United States Geological Survey (USGS) sampled the lower part of the Upper Cretaceous Lewis Shale in the eastern part of the Southwestern Wyoming Province to better characterize its petroleum source rock potential for an upcoming resource assessment. Ninety-five samples from 24 wells were collected from well cuttings of the lower part of the Lewis Shale stored at the U.S. Geological Survey Core Research Center in Lakewood, Colorado. The selected wells are located near the shallow margins of the basin to obtain samples that were not subjected to the effects of deep burial and subsequent organic carbon loss due to thermal maturation as described by Daly and Edman (1987) (fig, 1). The sample intervals were...
