This report deals with a shortcut graphical method for the quick determination of oil recovery versus cumulative water injected for a five-spot waterflood. Using only graph paper and a desk calculator, performance forecasts can be completed in about 30 minutes. Results are within an average of 2 percent of performance calculated by an electronic computer, a high degree of accuracy for a graphical method.
