Abstract
This study explores pressure, miscibility, and pore medium effects on heavy hydrocarbon recovery up to 65 MPa from four rock types: sand, tight sandstone, cavernous limestone, and oil sand. Results reveal MMP at 50 MPa, with peak recovery at 93% (56 MPa). Interestingly, recovery trends counter traditional expectations, notably decreasing in tight sandstone (42-56 MPa) and oil sand (50-65 MPa). Varied recoveries in cavernous limestone (25-56 MPa) highlight porosity and vug influence. Higher pressures hinder recovery due to SC-CO2's density and viscosity, favoring the immiscible process for efficient heavy hydrocarbon extraction.
