Abstract:
1. A method suitable for at least enabling the measurement of a property of a porous rock, the method comprising the steps of: (a) providing a porous rock core having a length, an inlet face, and an outlet face; (b) saturating the porous rock core with a first fluid; (c) displacing the first fluid by applying a second fluid to the inlet face of the porous rock core; (d) washing the outlet face of the porous rock core with said second fluid so as to maintain an outflow boundary condition; (e) determining that a substantially steady-state condition has been reached where the fluid saturation distribution and pressure distribution along the length of the core do not substantially change with time; (f) performing a fluid saturation distribution measurement of the porous rock core comprising the act of: (g) performing a pressure distribution measurement of the porous rock core; and (h) determining a property of the porous rock core by using fluid saturation measurement.
