Gas Lift Valves Functions
Dome pressure and throughput for injection-pressure-operated valves.
6 functions
PO.GL.Valve.Pdome(Pd_s, Ts, Td)
Calculates dome pressure at depth from surface dome pressure, [psi].
PO.GL.Valve.TRO(Pd, Td, R)
Calculates test rack opening pressure at 60°F, [psi].
PO.GL.Valve.Pvc(Pd, R)
Calculates valve closing pressure, [psi].
PO.GL.Valve.Spread(Pvo, Pvc)
Calculates valve spread (opening minus closing pressure), [psi].
PO.GL.Valve.ThornhillCraver(Cd, Ap, P1, P2, SG, T)
Calculates gas throughput using Thornhill-Craver equation, [Mscf/d].
PO.GL.Valve.PPE(R)
Calculates production pressure effect factor (PPEF), [dimensionless].
