... that the ultimate oil recovery of WAS scheme is higher in comparison with the SWAS, and the efficiency of solvent-soak goes further. The WAS scheme resulted in more oil recovery in comparison with the continuous solvent injection at the same value of solvent consumption. Good agreements observed between simulation...

In this study, a pragmatic method is developed to efficiently design the production-injection parameters for optimizing the WAG performance...

... concentration of only 0.2 wt% gave better recovery efficiency 18.7% OOIP than the polymer-alone flood. Moreover, it had much better gas utilization than the CO2 WAG run, consuming only 2.0 MSCF/stb, or one-third of the amount of CO2 used in that run to recover the same amount of oil. This performance...

.... Macroscopic displacement efficiency of solvent floods at various strongly wetted media by considering the effect of connate water has been studied. Influence of effective pore geometry parameters on oil recovery and microscopic displacements was investigated during miscible floods. Precise analyses...

Overall success has been limited. Beam pumps that replace ESP installations after initial dewatering have not matched the gas production when...

... is to experimentally investigate the propane flooding efficiency and applicability for Lloydminster type heavy oil reservoirs. A series of model tests were conducted to simulate the performance obtained when gravity effects were present. Based on the fact that the target reservoirs pressure ranges from 500 kPa to 1000...

... effective on the efficiency have been focus of many studies over the last four decades. Huang and Tracht (1) studied oil recovery mechanisms during CO 2 injection and reported that the dominant controlling mechanisms are CO 2 swelling and the CO 2 extraction of oil.

The cutting efficiency of a single PDC cutter is defined as the ratio of the rock volume removed by a cutter to the force required to remove that volume of rock. The cutting...

... waterflooding, technically feasible. Waterflooding has been tried in such reservoirs with limited success. The biggest problem encountered in waterflooding is the poor sweep efficiency and very rapid increase in the water/oil ratio in the produced fluid 3 . Indeed, most of the oil in such waterflooding...
