... for steam floods or as a steam additive. Experimental measurements were carried out at 69.8°F (21°C), the reservoir temperature, and at 284°F (140°C). The saturation pressures were between 400 psi (2.8 MPa) and 1,500 psi (10.3 MPa). At each pressure level the solubility of CO 2 in the oil, the density...

..., the viscosity of methane and ethane saturated water and brine has been measured at 100, 150, and 250°F over a pressure range of 0-7,500 psig. For methane in pure water, viscosity increases by up to 6% . At pressures above 2,000 psig, the viscosity is independent of saturation pressure. Dissolved ethane showed...

.... The normal concept of average reservoir saturation pressure disappears in model studies. Figure 1 shows how a reservoir may be sub-divided into blocks for a two-dimensional study. The pressure and saturation and the resulting fluid flow are calculated at each block over short time steps. As an area...
