3 lambdas
PO.VFP.Orkiszewski.dPdL.SI(Ql, Qg, P, Rho_l, Ul, Bl, Rho_g, Ug, Bg, IFT_gl, Rs, pipe_ID, pipe_roughness)
Calculates pressure gradient using Orkiszewski (1967) correlation, [kPa/m]. Vertical wells, widely used industry standard (SI units).
PO.VFP.Orkiszewski.Pout.SI(Ql, Qg, P_in, T, Rho_l, Ul, SG_gas, IFT_gl, pipe_ID, pipe_length, pipe_roughness)
Calculates outlet pipe pressure using Orkiszewski (1967), [kPa]. Vertical wells. Gas properties (ρg, μg, Bg) use DAK (Z-factor) and LGE (viscosity) (SI units).
PO.VFP.Orkiszewski.Pin.SI(Ql, Qg, P_out, T, Rho_l, Ul, SG_gas, IFT_gl, pipe_ID, pipe_length, pipe_roughness)
Calculates inlet pipe pressure using Orkiszewski (1967), [kPa]. Vertical wells. Gas properties (ρg, μg, Bg) use DAK (Z-factor) and LGE (viscosity) (SI units).
