Abstract

Fluid filtration and mass transfer processes description are the key issue of the geological modeling and oilfields development design for reservoirs with complex structure. The well log data interpretation results are the basis of reservoir characterization. The advanced application of the effective porosity value provides description of reservoir properties for dynamic (effective and relative permeabilities, capillary pressures, free fluids) reservoir simulation. The outcome values of effective porosity and clay swelling index are properties, which confidently reflect filtration reservoir parameters. It is stated that effective porosity determined with log data provides evaluation of relative/phase permeability values and hydrocarbon distribution in transition zones using capillary pressure models. The application of Buckley Leverett function for known effective permeability gives evaluation of oil share in production. It is established that effective porosity has strong correlation with productivity index for wide range of clastic reservoir rocks from different region. Thus, the determination of effective porosity from well logs is resulted in prediction of oil and water amounts in production. Obtained results are applied for fluid filtration processes modeling and reservoir development technology design for Urengoy Arch field.
