Abstract
One of the main parameters in modeling of two phase gas and oil flow is an accurate relative permeability functions. This importance will be more intensified when the miscibility condition approaches. In miscible condition due to reduction of interfacial tension between oil and gas phases, parameters of conventional relative permeability functions will change and this changing affects on production results such as oil and gas recovery and also pressure drop along the core. All of the previous studies could not present a unique and consistent model to show the effect of near miscibility condition on relative permeability curves. In this work, these changing of parameters will be investigated...
Experimental Study and Modeling of the Two - Phase Relative Permeability of Oil - Nanosilica/Polymer, Oil-Alkaline/Polymer, Oil - Alkaline/Nano-Silica/Polymer

Abstract
Oil reservoir Protection and production optimization requires the proper use of EOR methods. One of the conventional methods of EOR is chemical flooding (for example polymer, alkaline – Polymer, Nano - Polymer and Alkaline - Nano – Polymer flooding) which used for controlling mobility ratio of fluid within a reservoir, altering surface tension between fluids, and change reservoir wettability. On the other hand prediction of oil production in reservoirs during chemical injection processis impossible without having two-phase relative permeability functions and meanwhile, data from the experimental results of these functions are limited.In this study, effect of polymer type and concentration in...
