-Figure : The enclosed Pressure and Saturation contour plots correspond to the simulation of the Nechelik reservoir (80 X 75 cells) with 6 wells (2 horizontal, 4 vertical) for 1000 days with a time step of 0.1 days. After 500 days, water is being injected into two wells on the bottom left for secondary recovery.
