... numerical simulator is developed to model this process. The capillary pressure, relative permeability and residual saturations of both phases are considered as functions of IFT and wettability, which are correlated to the surfactant and salt concentrations based on the data obtained from laboratory...

... severely, and rock wettability (relative permeabilties) strongly influences oil recovery. These results indicate that accurate viscosity and relative permeability measurements are essential for a reliable performance prediction. relative permeability recovery oil recovery viscosity enhanced...

... Abstract Relative permeability provides important information for understanding the dynamic behavior of two-phase flow. EOR technology featured by polymer flooding, surfactant flooding and ASP compositional flooding requires relative permeability data to characterize the flow behavior...

... the analysis of a detailed laboratory study, designed to provide data for verifying hysteresis models for such simulations. A number of studies have reported evidence for hysteresis in gas relative permeabilities in WAG flooding, leading to lower gas mobilities than predicted by conventional two-phase models...

... Abstract In order to model a WAG process in a North Sea oil field integrated pore-to-field scale multiphase upscaling was performed [1] . The upscaling procedure included two steps. A pore-to-core upscaling step was based on pore network modeling. It resulted in relative permeabilities...

... that recovery efficiency is a function of rate as well as WAG ratio. We also find that the water-oil and the water-solvent relative permeabilities are not the same for the analogue fluids used. This is despite the fact that the oil and solvent are first contact miscible. If this is true for reservoir fluids...

..., the small-scale heterogeneities have to be accounted for through the so-called effective absolute and relative permeabilities. Generally, the effective relative permeabilities are rate-dependent [17] , [13] , [8] , [3] . We have developed a software package which computes the effective absolute and also...

... due to the movement of the sand particles. A relative permeability reduction after a certain period of production may result in a pressure gradient increase, which can promote further sand flow. This process can further improve the absolute permeability and the overall slurry production. Our results...

... Abstract The triple porosity reservoir investigated is unique with its highly heterogeneous carbonate characteristics. The largest hydrocarbon bearing formations are not only naturally fractured, but also highly vuggy. Special relative permeability, capillary pressure, and compressibility...
