- Total formation volume factor below bubblepoint pressure
Total formation volume factor below bubblepoint pressure is the volume at reservoir conditions occupied by
one stock tank barrel of oil, its remaining solution gas, and the free gas (Rsb - Rs) that has evolved from
the oil. In equation form,
The gas FVF can be calculated using the Z-factor.
Three methods for estimating total formation volume factor below bubblepoint pressure are presented.
