Fracture Characterization and Modeling of a Tight-Carbonate Reservoir

摘要

The Najmah/Sargelu reservoir of west Kuwait is a tight-carbonate oil reservoir in which porosity and permeability result from the fracture network.A mul-tidisciplinary integrated approach combined geology [borehole-imaging(BHI)logs,cores,and wireline logs),geophysics [seismic facies analysis(SFA)],and reservoir-engineering data [production,production-logging-test(PLT),and well-test] to identify the main types of fractures,to predict their occurrence in the reservoir,and to determine the hydraulic properties of the different fracture types.
