... relative permeability. Mathematic models of three phase relative permeability were proposed. The results show that oil phase isoperms is concave to 100% oil saturation. Water phase isoperms and gas phase isoperms are straight lines. Additionally, the scope of oil phase isoperms indicates that three phase...

... by low salinity waterflooding due to the double layer expansion. The relative permeability curves obtained by history matching showed that LSW improves oil recovery by accelerating oil production (relative perm changes) and reducing residual oil saturation in slight water-wet rock but not in strong water...

... stretched, the polymer may remain in that conformation for several relaxation times, a phenomenon known as coil-conformation hysteresis. ( Schroeder, et al., 2003 ) Displacement efficiency E d is limited by residual oil saturation which in turn is determined by the balance between mobilising (viscous...

Results showed that compared to shallow aquifer water, low-salinity water exhibited a higher oil relative permeability and lower water relative permeability at the same water saturation and a lower residual oil saturation to water. Laboratory results were input into a reservoir simulator to investigate...

It is assumed that the surfactant is able to solubilise oil which implies that a solubilisation shock develops between the injected composition...

In the field-scale application of the Surfactant Alternating Gas (SAG) process, multiphase fluid behavior in porous media is modeled using three-phase compositional relative permeability and three-phase hysteresis models to include both compositional and saturation history effects...

Approximate parity of relative mobility of injected fluids was observed with respect to relative mobility of displaced water at true residual oil saturation and interpreted relative mobility of a formed oil bank. These results indicate that in-situ foam propagation was present which enabled...

We found that the ultimate residual oil saturation in most experiments is similar to the case without gas. When free gas is present in the porous medium...
