eng.gas-well-deliverability-AOF Calculator
Calculates gas well Absolute Open Flow (AOF) potential from multi-rate deliverability test data. AOF is the theoretical maximum flow rate at zero wellbore pressure — it's not achieved in practice but sets the upper bound for well capacity planning.
Inputs
Pr Mpa
Force per unit area (Pa). Atmospheric pressure at sea level: 101,325 Pa. Check whether gauge or absolute pressure is required.
Pwf Mpa
Force per unit area (Pa). Atmospheric pressure at sea level: 101,325 Pa. Check whether gauge or absolute pressure is required.
C Const
Force per unit area (Pa). Atmospheric pressure at sea level: 101,325 Pa. Check whether gauge or absolute pressure is required.
N Exp
Force per unit area (Pa). Atmospheric pressure at sea level: 101,325 Pa. Check whether gauge or absolute pressure is required.
Results
flow rate Q (10⁶ m³/day)
Flow rate Q — the volume of fluid passing a point per unit time.
absolute open flow AOF (10⁶ m³/day)
Sample size or count used in the calculation.
(P_r² − P_wf²) (MPa²)
Reference formula or conversion factor shown for context.
deliverability ratio Q/AOF
The proportional relationship between two quantities.
Q = C·(Pr² − Pwf²)^n
Sample size or count used in the calculation.
n interpretation
Qualitative summary of what the computed numbers mean in practical terms.
