... is the productivity index, and FE is the flow efficiency, defined as the ratio of the actual productivity index to the ideal productivity index for flow with zero skin (no near well damage or stimulation). Equation 4 can also be used for mixed flow of dead oil (pressure above oil bubble point pressure) and water...
