P22 APPLICATION OF DOE TO STUDY IMPACT OF DISPERSION AND MISCIBILITY IN WAG Abstract 1 In this study the sensitivity of WAG (Water-Alternative-Gas) cycle time slug size permeability heterogeneities and correlation length are investigated using a series of simulation runs defined by experimental design 1 2 . As a result the obtained proxy model consists of four governing parameters that reveal the major sensitivities during the WAG process. This allows the prediction of the effect of dispersion and WAG parameters on the miscibility and the resulting recovery respectively. Water-Alternative Gas floods (WAG) are commonly used to improve sweep efficiency in
