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.
