PO.MBE.Exp.Bt.SI
Description
Calculates two-phase formation volume factor (Bt), [rm3/sm3]. Bt = Bo + (Rsi-Rs)*Bg (SI units).
Formula
=LAMBDA(Bo, Rs, Rsi, Bg, LET(
Rs_scfSTB, PO.UnitConverter(Rs, "sm3/sm3", "scf/STB"),
Rsi_scfSTB, PO.UnitConverter(Rsi, "sm3/sm3", "scf/STB"),
Bg_bblft3, PO.UnitConverter(Bg, "m3/m3", "bbl/ft3"),
PO.MBE.Exp.Bt(Bo, Rs_scfSTB, Rsi_scfSTB, Bg_bblft3)))Parameters
