PO.IPR.VW.PSS.AOF.ByFetkovich.SI


Description

Calculates Fetkovich maximum flow rate (AOF) at Pwf = 0, [m3/d]. Fetkovich (1973) correlation (SI units).

Formula

=LAMBDA(C, n, Pres, LET( C_field, C * PO.UnitConverter(1, "psi", "kPa")^(2*n) / PO.UnitConverter(1, "STB/d", "m3/d"), Pres_psi, PO.UnitConverter(Pres, "kPa", "psi"), result_STBd, PO.IPR.VW.PSS.AOF.ByFetkovich(C_field, n, Pres_psi), PO.UnitConverter(result_STBd, "STB/d", "m3/d")))

Parameters

Parameter Unit Description
C m3/(d·kPa^2n) Performance coefficient, [m3/(d·kPa^2n)]
n - Flow exponent (0.5 to 1.0), [dimensionless]
Pres kPa Average reservoir pressure, [kPa]
