Choosing optimal development scenario is one of the most important tasks in case of a fluvial reservoir. Well configuration factors that can influence reservoir connectivity are well density, well orientation and length of completion zones. Therefore length of deviated well path and its major direction are the main parameters for searching of the most robust development scenario. Optimization is based on three geological descriptions representing one of three algorithms (SIS, OBJ, MPS) and having minimum absolute error for the test wells. Parameters of each development scenario are optimized to reach maximum field oil production through 1000 realizations of differential evolution. Ranges of parameters distribution give useful trends showing the robustness on different geological descriptions.
