...) injection is performed in the form of water-alternating gas rather than continuous injection of expensive injectant. In this case, the process should be optimally designed for slug sizes and proper sequences of the solvent considering several controlling parameters including past history of waterflooding...

..., the positive sweep efficiency effect of low salinity injections takes over the negative permeability damage effect. Thus, the recovery curves for continuous fresh water injection and large slug sizes of 1.0, 0.5 and 0.25 PVI over takes the recovery curve for normal water-flood and remain above up to the end...

... oil recovery. In order to reach this goal, the reservoir engineering factors that affect the recovery efficiency are defined first. These field parameters considered the most relevant and chosen for this study are the injected bacteria concentration, the adaptation time, the optimum slug size...

Optimizing the slug size was repeated for different surfactant concentrations until an optimum concentration was also reached. In this study, the surfactant concentration...
