This report describes the gas potential of shales within the Pennsylvanian Paradox Formation of the Paradox Basin, southeastern Utah. Core descriptions, thin section and scanning electron microscopy evaluations, X-ray diffraction, geochemical measurements (total organic carbon and Rock-Eval pyrolysis), and rock mechanic analysis (triaxial compressional testing and static and acoustical evaluation) are reported for the Hovenweep, Gothic, and Chimney Rock shales from two wells in the basin. The results can help determine in-situ stress regimes and mechanical properties (with subsequent utility for stimulation and completion design [hydraulic fracturing, log calibration and horizontal well stability]) of this emerging shale-gas play.
