  7. Abstract:
  8. Accurate prediction of relative permeability for various reservoir rocks at various saturation conditions has been of concern for a long time in petroleum industry. Relative permeability is known as one of the most significant parameters in simulation of actual multi-phase flow through porous media during life-time of a hydrocarbon reservoir. In addition, it plays important role in oil production and well completion. Direct experimental measurement in order to determine relative permeability of porous rock has long been recorded in petroleum related literature. However, empirical methods for determining relative permeability are becoming more widely used, particularly with the advent of digital reservoir simulators. Three—phase relative permeability’s have an important role in numerical simulation of oil recovery processes. Thermal methods for heavy oil recovery, such as steam injection and in situ combustion, involve simultaneous flow of oil, water and gas at high temperatures. The objectives of this work were to develop an experimental apparatus for measuring three—phase relative perrneabilities to carry out such measurements in a model system. The rock—fluid system used in these measurements comprised Bria sand ston— refined mineral oil— distilled water — nitrogen gas
