Experiment and Numerical Simulation of Japanese Heavy Oil Recovery

Kreangkrai Maneeintr, Kyuro Sasaki, Yuichi Sugai

Abstract

Heavy oil production depends on reservoir characteristics like permeability, reservoir pressure and oil viscosity, Heavy oil is difficult to produce because of its high viscosity. To reduce viscosity, the suitable technology for producing this oil is thermal recovery by using steam. In this study the viscosities of oil were measured and correlated with temperature. Also the effects of reservoir characteristics were then studied by using a commercial reservoir simulator. The simulation results showed that oil viscosity and permeability play significant roles in heavy oil production whereas pressure difference has less effect on oil production.
