Introduction The ISAPP field development optimization challenge has been developed with the goal of benchmarking field development optimization workflows and algorithms. ISAPP (Integrated Systems Approach to Petroleum Production) is a joint project of TNO, Delft University of Technology, ENI, Statoil and Petrobras. Three different optimization optimization problems have been formulated as follows: Well Control Optimization – Optimize the controls of 7 water injection wells and 11 oil producers. The location of the wells are fixed for this problem and only the well controls are to be optimized.
