Brief

The general form the Oil Material Balance equation was first published by Schilthuis in 1941[1].

Math & Physics

Production mechanism - gas compressibility only:

 GIIP \times B_{gi}= (GIIP - G_p) B_g

Nomenclature

 B_g = gas formation volume factor, ft3/scf
 B_{gi} = initial gas formation volume factor, ft3/scf
 GIIP = gas initially in place, scf
 G_p = cumulative gas produced, scf
