Simulation of Water and Gas Injection in an Oil Reservoir Intermittently<\/a><\/h3>\n

Abstract<\/b><\/p>\n

<\/b>In this paper, Simulation of water and gas injection was examined in an oil reservoir intermittently. Scenarios of water injection and gas injection were simulated separately and their results were compared with each other and with intermittent water and gas injection. CMG software was used in this article for reservoir simulation. Builder tool was used to make physical model and WinProp for making fluid model, and GMT simulator for making simulation of enhanced oil recovery processes. The results show that the coefficient of productivity and cumulative production is more than other scenarios of injection in the injection cycle of 4: 2. Investigations in the field of study show that the productivity coefficient will be more if the period of gas injection be higher than water. In WAG method if injection of gas to be done sooner than water (water phase as a secondary fluid be injected to the reservoir), production and efficiency increase compared to the state that injection of water earlier and as a first fluid be injected to the reservoir. Higher efficiency and production in IWAG method, compared to the other injection WAG methods show higher movement of sweep whether microscopic and macroscopic, and higher efficiency in this method compared to other methods of injection. Productivity coefficient and cumulative production of WAG method is higher compared to normal production methods, water and gas injection, therefore this method was introduced as an optimal enhanced oil recovery in the field of study.<\/p>\n
