Reservoirs in the Weicheng Oilfield, which occur in Paleogene Shahejie Formation Member 4 (Es4), were formed during the initial and strongly rifting stage of the Dongpu Depression. The geometry and distribution of sands of different types have controlled the heterogeneity of the reservoirs and have resulted in exploration challenges and relatively low recoveries. Based on various static and dynamic...
The geologic reservoir fine description and reservoir engineering approaches are combined to study the structure characteristic, the sedimentary facies and the distribution of the remaining oil in the lower-middle series of strata of Hetaoyuan formation in Xiaermen Oilfield. First the detailed distribution of the microfacies is studied based on core description and petrophysical analysis. Then the...
