Abstract This thesis studies the effect of confinement on the PVT properties of hydrocarbon fluids in tight and shale reservoirs. The study finds that rich natural gases exhibit more significant deviations in physical properties than lean natural gases when confined. Confinement impacts gas compressibility factor, viscosity, and density, with the greatest effect observed under high pressure, low temperature, small pore radius, and rich gas composition. The PVT study shows that confinement results in a depression in bubble point pressure, lower oil viscosity and density, and higher gas solubility and formation volume factor, highlighting the importance of considering capillary pressure and critical properties shift in understanding hydrocarbon behavior in tight reservoirs. |
