Experimental study of phase behavior: Heavy oil mixed with hydrocarbon solvent

Sun, Min (RPL, University of Houston) | Han, De-hua (RPL, University of Houston)


Summary The phase behavior of the heavy oil (12 wt.%) mixed with hydrocarbon solvent (88 wt.%) has been investigated experimentally via in-situ P-wave velocity and density measurement, density measurement of gas-exhausted oil, and phase behavior observation. Suspended asphaltenes are hardly identified by velocity and density measurement, but their deposition and solidification have been observed at a typical in-situ condition, 22 C and 5 MPa.
