A novel in-situ method for measuring molecular diffusion coefficients of CO/sub 2/ a other solvent gases in consolidated porous media at high pressure has been developed and is described. This technique is unique because visual observations and measurements of composition are not required. Experimental diffusion coefficients are reported for CO/sub 2/ in decane up to 850 psia (5.86 MPa), for CO/sub 2/ in 0.25N NaCl brine up to 850 psia (5.86 MPa), and for ethane in decane up to 600 psia (4.l4 MPa) All tests were conducted in Berea cores saturated with the liquid phase at 100/sup 0/F (311 K). Cores were oriented both vertically and horizontally to assess the effects of gravity-induced convection on the observed mass transfer. The experimental diffusion coefficients obtained from this study have also been correlated, together with literature data for methane, ethane and propane, as a function of liquid viscosity and thermophysical properties of the diffusing gases.
