As a result, hydrocarbon assessment for shale source rock plays have significant uncertainties. This study focuses on petrophysical interpretation uncertainty from a single historic Barnett Shale well TP Sims #2 of Wise County, TX. The Barnett Shale is one of the major source rock plays in the United States. The large body of research and information from the well-drilled Barnett Shale provides a good opportunity to understand and adjust OGIP modeling approaches from volumetric analysis to well performance data. Several factors unique to shale source rocks such as TOC and pyrite have been incorporated into wireline log interpretation using core-derived correlations. Key petrophysical parameters that are estimated from well logs calibrated to core data include: mineral volumes, porosity, net pay, and water saturation. Volumetric OGIP calculations from a range of well log analysis results that have been calibrated to core for TP Sims #2 are compared with EUR data. The resulting recovery factors are larger than expected which may mean that volumetric OGIP remains deficient for resource assessment of shale plays.
