Unformatted text preview: calculations are needed to make these sketches and you do not need to use the same data as used in the homework problem. (b) Show and explain in detail how to calculate the displacement sweep efficiency at exactly 1.5 pore volumes using the sketches you made in part (a) and the Welge method you used in homework#6. Assume the initial gas saturation is zero. (c) Make a sketch of the gas saturation profile at 1.5 pore volumes. (d) Make a sketch of the oil production rate (q o ) versus pore volumes that is consistent with your fractional flow sketch. Again, no calculations are needed to make this sketch, but it should be qualitatively consistent with your fractional flow diagram. (e) Sketch the displacement sweep efficiency versus pore volumes for your example and for two other examples with widely different mobility ratios to show how it changes with mobility ratio....
