Well Placement Optimization by Infill Drilling Using Streamline Simulation in an Iranian Oil Reservoir

Although nowadays finite difference simulators have many advantages for reservoir engineers to predict reservoirs in ٣ dimensions, they have some disadvantages; such as spending much run time for complex fields with several thousand grids which by using Streamline simulation, the run time was decreased a lot. In this paper, first a briefsummary of streamline simulation and its uniqueness applications were discussed and then an Iranian oil reservoir as a case study wassimulated by using FrontSim streamline simulator, then besides testing the results of Sayyafzadeh et al (٢٠١٠) to find the location of infillwells, the most suitable locations for infill drilling were selected, after that, vertical infill wells were investigated, and overally ٣ scenarioswere tested by converting ٣ producers to injectors and defining two well patterns. finally the results of simulation and testing infill drillingscenario shows significant increasing in field oil production and field oil recovery factor, approximately ١٤.٥%, and also reduction field water cut.
