Abstract:
Water injection is used in petroleum industry as a means to retain the reservoir pressure and to improve oil production. The water is injected into the reservoir via one or more than one injection well.
The location of injection well/wells in oil field is very important. Selecting the location of such wells has always been a question among researchers. It must be allocated in a proper way to enhance oil recovery as much as possible.
Using traditional methods to optimize such well locations is infeasible due to the complexity of the reservoir equations. By depleting the underground reserves, oil companies are inclined to preserve the production of oil and gas.
In this paper, a case has been studied and finding optimal well location has been investigated in order to increase the recovery factor.
In this case study, a non-uniform (irregular size grids) sector of an oil reservoir with two dimensional two phase (oil and gas) flow regime has been considered. In this reservoir, there is a strong aquifer which maintains border pressures at a constant amount. In a simulated part of this study, we use IMPES (Implicit Pressure, Explicit Saturation) method to solve equations and to obtain grid pressures and water saturation during time steps. We use MATLAB mathematical package for simulation and programming. Our main purpose in this study is to find the best location for water injection well on this oil field in order to increase oil production as much as possible.
