STREAMLINE SIMULATION FOR WELL PATTERN IMPROVING IN AN IRANIAN OIL RESERVOIR

Although nowadays finite difference simulators have many advantages for reservoir engineers to predict reservoirs in 3 dimensions, they have somedisadvantages; such as spending much run time for complex fields with several thousand grids which by using Streamline simulation, the run time wasdecreased a lot. In this paper, first a brief summary of streamline simulation and its uniqueness applications were discussed and then an Iranian oil reservoir as acase study was simulated by using FrontSim streamline simulator, then besides testing the results of Sayyafzadeh et al (2010) to find the location ofinfill wells, the most suitable locations for infill drilling were selected, after that, by converting 3 producers to injectors and considering Direct LineDrive and Staggered Line Drive patterns, vertical and horizontal infill wells were investigated in these twowell patterns and totally 3 basic scenarios besides 64minor scenarios were tested using Streamline simulation method and FrontSim software, finally theresults of simulation and testing infill drilling scenario shows significant increasing in field oil production and field oil recovery factor,approximately 14.5%, and also reduction field watercut. In addition, distinguishing fractures or faults, well's drainage area and understanding that how much injectors affect the field oil production are other benefits of Streamline simulation method
