Paper Number: PETSOC-2009-176
... to efficiently displace and produce water and oil retained in reservoirs after an enhanced oil recovery process. Many previous studies about CO 2 injection are related to enhancing oil recovery rather than improving CO 2 storage capacity [5–8] . Orr et al. [5] had a detailed discussion about mechanism of CO...

Paper Number: PETSOC-2009-001
... Abstract Vapor Extraction (VAPEX) a new developed Heavy Oil Recovery (HOR) method, has been extensively studied, both theoretically and experimentally, in conventional sandstone models. However, the applicability of this process on naturally fractured reservoirs has not been addressed yet...

... Abstract Alkaline flooding is a promising technique for enhancing heavy oil recovery, especially for thin reservoirs where other processes are not practicable. During alkaline flooding, oil recovery is increased by improving sweep efficiency as a result of in-situ formation of water-in-oil (W...

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...

..., and low ultimate oil recovery. Previous studies for achieving the optimum WAG performance are mostly limited to a certain well pattern or a small-scale problem. It is essential to conduct optimal parametric design to optimize the WAG performance for a field-scale problem. In this study, a pragmatic method...

... 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...

... Abstract Results of a reservoir 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 CO 2 injection...

... Abstract Carbon dioxide (CO 2 ) 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 recovery by means of swelling, evaporating...

TTH steamflooding with solvent proved superior to the TTH steamflooding, as the channeling of steam through the horizontal well was much better controlled, and the oil recovery...

Therefore, it is essential to study the effect of the variation in fluid properties such as oil viscosity and oil saturated pressure (or initial GOR) on the prediction of the heavy oil recovery performance from dynamic reservoir simulation. Implementation The approach...

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...
