  3. Abstract:
  4. As many fields around the world are reaching maturity, the need to develop new tools that allows reservoir engineering to optimize reservoir performance is becoming more demanding. One of the more challenging and influential problems along these lines is the well placement optimization problem. Determining of the location of new wells is a complex problem that depends on reservoir and fluid properties, well and surface equipment specifications, and economic criteria. Various approaches have been proposed for this problem. Among those, direct optimization using the simulator as the evaluation function, although accurate, is in most cases infeasible due to the number of simulations required. The optimization algorithm used in this work is the genetic algorithm which is a method based on natural evolution process. Optimal placement of up to three surfactant injection wells was studied at two fields. One of the Iranian conventional field and a hypothetic fractured field. The net present value of the surfactant and water flooding projects was used as the objective function. Profits and costs during the time period of the project were taken into consideration
