Prospect Evaluation of the Cretaceous Yageliemu Clastic Reservoir Based on Geophysical Log Data: A Case Study from the Yakela Gas Condensate Field, Tarim Basin, China

This paper evaluated the oil and gas potential of Cretaceous Yageliemu clastic reservoir within Yakela condensed field lying in Kuqa Depression, Tarim Basin, China. The petrophysical properties interest zones area were characterized using geophysical logs from five wells. results reveal that gas-bearing are by high resistivity, good permeability (K) effective porosity (?eff), low water saturation (Sw), shale concentration (Vsh), reflecting clean sand. distribution model showed these shales have no major influence on fluid saturation. average volume, porosity, hydrocarbon indicate Formation studied contains prospective properties. spatial parameters, rock typing (RRT), lithofacies analyzed cross plots litho (volumetric analysis), iso-parametric representations characteristics, cluster analysis, self-organizing feature maps, respectively. southeastern northeastern regions research should be ignored because their concentrations. sediments southwest northwest include most intervals considered for future exploration development fields study area.
