Experimental investigation of the effect of temperature on two-phase oil-water relative permeability

Relative permeability is affected by several flow parameters, mainly the operating temperature and fluid viscosity. Fluid viscosities change with temperature, which correspondingly affects relative permeability. Temperature believed to have a considerable effect on oil–water permeability, thus vital input parameter in petroleum reservoir production modelling. The actual of oil-water curves has been subject debate within scientific community. literature shows contradictory experimental numerical results concerning This work investigates using well-sorted unconsolidated silica sandpacks, adopting unsteady-state method, applying history matching technique. series experiments were conducted at different temperatures 40, 60, 80 °C under three levels injection rate (0.0083, 0.0125, 0.0167 cm3/s) for two oil samples. findings show that function water Generally, profile curve changes varying viscosity same condition.
