Correlations are presented which will aid in the forecasting of waterflood rate and reserves for 5-spot and line drive pattern configurations. Included in the correlations are the effects of mobility ratio, permeability variation, and areal sweep. Assumptions made in developing the correlations are no gas saturation at start of flood, no crossflow between layers, piston-like displacement, and constant layer porosity and displaceable saturation. It is shown by comparing the results from the correlations with actual case histories that the ultimate conformance is not substantially affected by an initial gas saturation and the correlations can be applied fields with an initial gas saturation. The correlations provide a ratio of injection rate at breakthrough to injection rate at various sweep efficiencies so that rate can be forecast during the life of the flood.
