... was performed using two stacked plugs from Field A at 279 °F and an injection pressure of 3000 psig. After cleaning with a 50:50 Toluene-Methanol mix, the core plugs were saturated with synthetic formation water. Once saturated, the core plugs were aged in Field A reservoir fluid (Oil A) for 40 days...

... of the three depressurisation regimes. Introduction In solution gas drive, bubbles nucleate and grow within saturated oil when the reservoir pressure is lowered below the bubble point. A period of internal gas-phase expansion maintains reservoir pressure, driving oil to the wellbore region. After some time...

The retention of increased water saturation in the pore system after the injection of water-based completion fluids can restrict the flow...

... analyzed. At the end of this depletion period, the reservoir has a substantial amount of condensate that has dropped out from the produced gas, giving an average oil saturation of 0.19 in the model. The dew point pressure of this fluid is 5330 psia. The base case has injection of 40 Mscf/d of CO2...

.... The CO2 storage capacity in water as dissolved gas is much less than that of CO2 as supercritical gas. Meanwhile, the residual oil saturation after most tertiary recovery methods is still as high as 30%[4]. The remaining water and residual oil restrict the CO2 storage capacity in the depleted oil...

... is recovered as water in oil emulsion. The emulsion viscosity is greater than the oil viscosity (Vittoratos, 1991). This is more than compensated by the increased oil saturation (and therefore increased oil relative permeability) due to oil phase swelling resulting from the water in the emulsion. In later...

... of such effects. Theory Consider a block of reservoir rock saturated with oil and water. The edges of the block are impermeable. If capillary pressure is negligible and the oil is less dense than the water, all the oil will eventually rise to the top and of the block and all the water will sink to the bottom...

The high pressure and high temperature zone of the SAGD process should generate differences between the first (2002) and second (2006) Vp...

Upon flow back (production); many of the above factors are not fully reversed, leading to significant gas retention. It is surmised that generalized...
