FRACTURE FEATURES AND RESERVOIR HETEROGENEITY OF CARBONATE RESERVOIR IN EPC AREA, MEXICO

The area of EPC is located in the Tampico basin of Mexico, with the Cretaceous as its main reservoirs. Lithological study and FMI data are adopted for understanding the regional pattern of fracture system in order to assess the future development potential of the area. Our results show that the region is dominated by open and close fractures. The physical properties of the reservoir depend upon lithology, diagenesis, fluid properties and fracture system. As the result, the reservoir is heterogeneous in both vertical and horizontal directions.
