Abstract
In petroleum industry, water flooding is used as secondary recovery method to increase oil production. It is the most widely used and popular method due to easy water availability, ease of injection, and mobility, etc. but at later stages, it becomes uneconomical due to the cost of separation and treatment of the produced water. Hence, in order to maximize the oil recovery in an economical way from waterflooding, it is important to make some changes in the flooding pattern. The aim of the present study is to analyze the waterflooding performance for the enhancement of oil production of virtual reservoirs using CMG-IMEX (Computer Modeling Group) reservoir simulation tool. The performance analysis is done for different flooding layout (horizontal or combination of vertical and horizontal well) and of different length of injection and production well. Three parameters such as cumulative oil production, percentage water cut, and water–oil ratio are used to predict the performance. The fresh simulation performed for the condition available in open literature, called base case, is in good agreement with the earlier published results. Nine different alternative arrangements were simulated and the best combination is reported where the highest amount of cumulative oil production and highest percentage of enhancement of oil production can be achieved.
