Abstract: A method and apparatus for obtaining data for simultaneously measuring relative permeability (k.sub.r), static capillary pressure, dynamic capillary pressure (P.sub.c), and electrical resistivity (R.sub.t) of a core sample taken from a subterranean reservoir under simulated reservoir temperature and pressure. A core sample having a a simulated original water and oil saturation is waterflooded while (1) pressures at spaced points along the core are measured to determine k.sub.r, (2) capillary pressures of the oil and water are measured to determine P.sub.c ; and (3) R.sub.t is measured between points spaced on the core. At the same time, the core is scanned by microwaves to determine the water saturation existing in the core at the time a particular measurement is made.

Abstract: A first fluid having a dyed styrene monomer is injected into a porous reservoir rock to effect saturation. A second fluid, miscible with the first fluid and having a dyed styrene monomer differing in color from the first fluid, is injected into the porous rock to displace the first fluid. Effluent flow from the porous rock is monitored with UV-visible light spectroscopy for use in determining oil displacement characteristics of the porous rock. Subsequent rapid polymerization of the styrene monomer within the porous rock allows identification and characterization of the controlling factors and attributes of the pore network responsible for entrapment of the residual phase. This allows assessment of larger intervals of the reservoir rock.
