2. MWaof Mwaof uses standard back pressure test results and flow rates of gas plus liquids from individual wells and performs and Absolute Open Flow (AOF) analysis using four different analysis approaches. The program allow easy determination of AOF potential from different deliverability tests using graphical and numerical analysis. Analysis are summarised and sandface IPR is generated.
