Relative Permeability Study in Part of Geleki Oil field of Upper Assam Basin
Abstract: Relative permeability is a critical parameter for evaluation of reservoir performance. Relative permeability is a direct measure of the ability of the porous medium to allow flow of one fluid when two or more fluids are present. This flow property is the composite effect of pore-geometry, wettability, fluid saturation, saturation history, reservoir temperature, reservoir pressure, overburden pressure, rock-types, porosity and permeability types. The relative permeability curves are very important in …
