The goal of the study discussed in this paper was to investigate if a new proposed process coupling CO2 and polymer injection can increase EOR performance...

... condition core flood were matched by a compositional model. Using this model as a base case, the effect of gas composition on oil recovery from an onshore Australian oil field was investigated. Based on this and earlier studies it was found that CO2 injection in this field gave MMP values well within...

.... 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...

... Abstract Due to the favorable effects of CO 2 , such as oil viscosity reduction, oil swelling, and surface tension reduction, CO 2 injection has been established as an effective technique in enhanced oil recovery for light to medium oils. However the utilization of CO 2 for improving...

The objective of this paper was to evaluate the parameters affecting the storage capacity of CO2 from core scale experiments and simulations, thus to seek for methods to efficiently displace and produce water and oil retained in reservoirs after an enhanced oil recovery process. Many previous...

In addition, a validated numerical model based on laboratory data was developed to carry out some sensitivity analysis of different parameters which were difficult to perform on experimental setup. The results confirmed that the ultimate oil recovery of WAS scheme is higher in comparison...

Inappropriate selection of parameters for the WAG process can lead to unstable pressure distribution, early gas breakthrough, and low ultimate oil recovery. Previous studies for achieving the optimum WAG performance are mostly limited...

Abstract Carbon dioxide ( 2CO ) flooding is an efficacious method of enhanced oil recovery (EOR) that has nowadays become one of the most important EOR processes. It is a very complicated process, involving phase behavior that could increase oil...

The viscosity of oil samples used for different experiments ranged from 1000 to 8400 cP. The polymer solution used for this study was high molecular weight...

... through the horizontal well was much better controlled, and the oil recovery was considerably faster. With these improvements, the oil recovery increased from 50-54% to 75- 77%, and the operation became smoother. Presently, the process can be considered only for reservoirs where oil has some mobility...

The experiments showed that a hybrid solvent-steam process could recover bitumen at steamoil ratios much lower than those observed for SAGD, and achieve reasonable ultimate oil recovery (60% IOIP). The economic analysis based on experiments indicated that a hybrid solvent-steam...
