Nonlinear risk optimization approach to water drive gas reservoir production optimization using DOE and artificial intelligence

The results also indicate the higher performance of proposed method over the conventional uncertainty assessment methods to predict the most likely recovery factor. The prediction error of most likely recovery factor by applying GA, BBD, FFD, CCD, UD, and RVF is 0.11, 2.2, 3.15, 2.78, 7.22, and 11.4% respectively.
