... of VRR less than 1 (VRR <1) may be optimal for recovery. Laboratory evidence suggests that recovery for VRR <1 is enhanced by emulsion flow and foamy oil at pressures under bubble point for some crude oils. This paper investigates the effect of VRR for two crude oils referred to as A1 (88 cP...

...-channels increases the apparent molecular weight of the liquid in the nano-channels, suppressing the bubble point of the remaining fluid. A modified flash calculation procedure that uses the sizes of micro-channels and nano-channels as the characteristic lengths and assumed contact angle can reproduce...

... characterization tests were performed, including GOR, viscosity, density, compositional measurements and other PVT experiments. Average properties of the live oil used were GOR of 96 scf/STB, bubble point pressure of 1020 psia at 125 °F and viscosity of 1650 cP at reservoir conditions. In addition, several flow...

... the completion strategy significantly. To test the assumption of a constant-gas-compressibility, we extend such a study by introducing a fully coupled geomechanics model. In this model, a two-phase oil/water flow model is assumed above the bubble point, and the flow is fully coupled to the pore volume change...

... to reservoir oil produces a series of bubble point mixtures, then a critical mixture, and finally, a series of dew point mixtures. A bubble point mixture is defined as one which produces a gas as the second phase when the pres- sure is lowered into the two phase region. A dew point mixture produces a liquid...
