.... The Corey's model was used directly to predict oil/water relative permeability in the carbonate composite cores. A modified Corey model (proposed in this paper) was used to calculate water and miscible phase relative permeability and describe the flow behavior of sc-CO 2 . The effect of the Corey's exponents...

... (saturation exponent, n, and cementation exponent, m) is essential for better estimation of water saturation and log calibration especially for heterogeneous carbonates reservoirs. In this study, sixty (60) plugs recovered from different wells across an Arabian carbonate reservoir were used to evaluate...

... and saturation exponents, capillary pressure, relative permeability and elastic properties. A comprehensive DRP based validation study was performed on reservoir core plugs which had undergone rigorous Petrophysical SCAL at representative pseudo reservoir conditions. The objective was to assess the use of DRP...
