Gas Lift Injection Functions
Injection gas rate and pressure at depth.
4 functions
PO.GL.Inj.Pd(Ps, D, G)
Calculates injection gas pressure at depth, [psi].
PO.GL.Inj.Grad(SG, P, T, Z)
Calculates gas gradient in the annulus, [psi/ft].
PO.GL.Inj.Qgi(GLRt, GLRf, Ql)
Calculates required gas injection rate for target GLR, [Mscf/d].
PO.GL.Inj.Eff(GLRf, Qg, Ql)
Calculates total GLR including formation and injected gas, [scf/STB].
