Abstract
The paper presents the results of experimental study for determination of relative oil and gas permeabilities and capillary pressures by centrifuge experiments on six samples of fine-grained sandstone. The experiment included oil displacement by water in temperature and pressure conditions simulating those in situ. Centrifugation was conducted at six different rotor speeds until stable oil production was achieved. Endpoint saturations were obtained in a separate procedure. Permeabilities at initial and residual oil saturation were determined in core flood apparatus and gas permeameter, respectively. Relative permeability and capillary pressure during water displacement were estimated in CYDAR software.
