===Oil Formation Volume Factor===
Formation volume factor is the ratio of the volume of oil in the reservoir (include saturated gas) and the volume of oil on the surface. Oil in reservoir volume VR (include saturated gas) will changes into 2 phase fluid, it is oil stock tank volume VST and gas stock tank volume VGST. Ratio formation volume factor oil Bo expressed by:
