9 lambdas
PO.MBE.Exp.Eo.SI(Bo, Boi, Rs, Rsi, Bg)
Calculates oil and dissolved gas expansion term (Eo), [rm3/sm3]. Eo = (Bo-Boi) + (Rsi-Rs)*Bg (SI units).
PO.MBE.Exp.Efw.SI(Boi, cw, cf, Swc, m, deltaP)
Calculates formation/water expansion term (Efw), [rm3/sm3]. Accounts for rock compaction and connate water expansion (SI units).
PO.MBE.Exp.Bt.SI(Bo, Rs, Rsi, Bg)
Calculates two-phase formation volume factor (Bt), [rm3/sm3]. Bt = Bo + (Rsi-Rs)*Bg (SI units).
PO.MBE.F.Oil.SI(Np, Bo, Rp, Rs, Bg, Wp, Bw)
Calculates underground withdrawal for oil reservoir, [m3]. F = Np*(Bo + (Rp-Rs)*Bg) + Wp*Bw (SI units).
PO.MBE.Ce.UnSat.Oil.SI(co, cw, cf, Swc)
Calculates effective compressibility for undersaturated oil reservoir, [1/kPa] (SI units).
PO.MBE.Ce.Gas.SI(cw, cf, Sw)
Calculates effective compressibility for gas reservoir, [1/kPa] (SI units).
PO.MBE.Ce.Geopressured.SI(cw, cf, Sw, Rsw, Bg)
Calculates effective compressibility for geopressured reservoir with gas solubility, [1/kPa] (SI units).
PO.MBE.Ce.PoreVol.SI(cw, cf, Swc)
Calculates pore volume compressibility term, [1/kPa]. cpv = (cw*Swc + cf) / (1 - Swc) (SI units).
PO.MBE.Ce.Total.SI(cg, cw, cf, Sg, Sw)
Calculates total system compressibility, [1/kPa]. ct = Sg*cg + Sw*cw + cf (SI units).
