Abstract This experimental study focuses on the variation of the salinity and the injected volume of individual WAG miscible flooding scheme for the improvement of oil recovery. In total, three slug sizes and five salinities were investigated in WAG flooding cycles and the recovered oil was measured accordingly. A response surface function was introduced for the purposes of estimating the available design and finally optimizing the variables. The experimental results indicated the unstable performances of oil recovery to the variations in the design parameters, confirmed the dependence of the oil production on a nonlinear function of the salinity and injected volume.
