PO.MBE.Exp.Eo(Bo, Boi, Rs, Rsi, Bg)

Calculates oil and dissolved gas expansion term (Eo), [RB/STB]. Eo = (Bo-Boi) + (Rsi-Rs)*Bg.

PO.MBE.Exp.Eg(Boi, Bg, Bgi)

Calculates gas cap expansion term (Eg) for oil reservoirs, [RB/STB]. Eg = Boi*(Bg/Bgi - 1).

PO.MBE.Exp.Eg.Gas(Bg, Bgi)

Calculates gas expansion for pure gas reservoirs, [RB/scf]. Eg = Bg - Bgi.

PO.MBE.Exp.Efw(Boi, cw, cf, Swc, m, deltaP)

Calculates formation/water expansion term (Efw), [RB/STB]. Accounts for rock compaction and connate water expansion.

PO.MBE.Exp.Et(Eo, Eg, Efw, m)

Calculates total expansion term (Et), [RB/STB]. Et = Eo + m*Eg + Efw.

PO.MBE.Exp.Bt(Bo, Rs, Rsi, Bg)

Calculates two-phase formation volume factor (Bt), [RB/STB]. Bt = Bo + (Rsi-Rs)*Bg.
