What is gas formation volume factor?

Gas formation volume factor is defined as the ratio of gas volume at reservoir condition to the gas volume at standard condition, that is,(2.62)Bg=VVsc=pscpTTsczzsc=0.0283zTp,where the unit of formation volume factor is ft3/scf.

What is total formation volume factor?

The oil formation volume factor, Bo, is defined as the ratio of the volume of oil (plus the gas in solution) at the prevailing reservoir temperature and pressure to the volume of oil at standard conditions. Bo is always greater than or equal to unity.

What is water formation volume factor?

PetroWiki. The produced water formation volume factor (FVF), Bw, is defined as the volume at reservoir conditions occupied by 1 stock tank barrel (STB) of formation water plus its dissolved gas. It represents the change in volume of the formation water as it moves from reservoir conditions to surface conditions.

What is the significance of gas volume factor?

Formation volume factor (FVF) is a useful relationship for relating gas volumes in the reservoir to the produced volume at standard conditions. Formation volume factor also enables the calculation of density.

How is the volume of gas related to formation?

The gas formation volume factor is used to relate the volume of gas, as measured at reservoir conditions, to the volume of the gas as measured at standard conditions, that is, 60°F and 14.7 psia.

How is the formation volume factor ( FVF ) calculated?

Gas Formation Volume Factor is the formation volume factor (FVF) that relates the volume of gas in a reservoir with the volume of gas which actually got produced during the standard operating conditions. It is one of the important parameters which have to be calculated during the production of natural gas from a gas well.

Which is true of the oil formation volume factor?

Oil Formation Volume Factor. The oil formation volume factor, B o, is defined as the ratio of the volume of oil (plus the gas in solution) at the prevailing reservoir temperature and pressure to the volume of oil at standard conditions. B o is always greater than or equal to unity.

What is the formula for gas formation factor?

Nomenclature Bg = gas formation volume factor (RB/scf or R mg = mass of gas, kg Ma = molecular weight of air Mg = average molecular weight of gas mixture n = number of moles
