  • Identification of reservoir availability and quantitative assessment are some of the most critical issues in tight sand oil and gas exploration.

Abstract: Identification of reservoir availability and quantitative assessment are some of the most critical issues in tight sand oil and gas exploration. Multiple analysis scales from the microscale, drill core to well logging have been conducted to examine the reservoir heterogeneity of the first member of the Upper Paleozoic Shanxi Formation in the southeastern Ordos Basin. Three sandstone petrofacies have been defined in the gas reservoirs. Ductile grain-lean sublitharenite forms reservoir rocks with good petrophysics and gas show. A model based on principal component analysis has been constructed to predict high-quality reservoir rocks and understand their spatial distribution patterns using well logs corrected from thin section and drill core data. The micro-scale description of the petrofaceis has been upscaled for field-scale characterization, and the availability of tight gas sandstone reservoir has been quantitatively assessed.
