# What is total formation volume factor?

## What is total formation volume factor?

Oil formation volume factor is defined as the volume of oil (and dissolved gas) at reservoir pressure and temperature required to produce one stock tank barrel of oil at the surface.

## What is two phase formation volume factor?

From the figure above it should be clear that the two phase oil formation volume factor ( ) is the total volume at reservoir conditions (liquid phase + gas phase) divided by its resulting oil-phase at standard conditions.

Which two factors influence the gas formation volume factor?

Formation Volume Factor It is a very strong function of pressure, and a weak function of temperature and gas composition. The dry gas formation volume factor is the gas volume at reservoir conditions divided by the gas volume at standard conditions.

### What is BT in reservoir engineering?

The total formation volume factor is defined as. Bt = volume of oil + free gas at reservoir conditions / volume of oil at standard conditions.

### What is BG in oil and gas?

The formation volume factor of a natural gas (Bg) relates the volume of 1 lbmol of gas at reservoir conditions to the volume of the same lbmol of gas at standard conditions, as follows: Bg=Volume of 1 lbmol of gas at reservoir conditions, RCFVolume of 1lbmol gas at standard conditions, SCF.

How do you calculate formation factor?

Unless otherwise stated, the term formation factor usually refers to the apparent formation factor. F has been related to porosity (phi) by several formulae (Archie, Humble and others) that have the general expression F = a / phim, where a is a constant and m the porosity exponent.

#### What is Bo Petroleum?

2 thoughts on “Formation Volume Factor (Bo)” “The formation volume factor is defined as the oil liquid volume at reservoir conditions divided by the oil liquid volume of the same sample at reservoir conditions.”

#### How do you calculate oil to gas ratio?

For a 50:1 ratio of gas to oil, use 2.6 fluid ounces of oil per gallon of gas. For a 40:1 mixture, use 3.2 fluid ounces of oil per gallon of gas. For a 32:1 mixture, use 4 fluid ounces of oil per gallon of gas.

What is the gas factor?

The gas correction factor (GCF) is used to indicate the ratio of flow rates of different gases for a given output voltage from a mass flow controller (MFC). The basis gas is nitrogen (N2) which, by convention, has GCFN2 = 1.

## What is RB STB?

RB = reservoir barrels. STB = stock tank barrels.

## What is a formation factor?

Formation factor is the ratio of pore solution conductivity and bulk conductivity of concrete (or the ratio of bulk resistivity to pore solution resistivity, the same thing). Bulk conductivity is the conductivity of concrete as a composite.

What do you mean by formation factor?

1. n. [Formation Evaluation] The ratio of the resistivity of a rock filled with water (Ro) to the resistivity of that water (Rw). G.E. Archie postulated that the formation factor (F) was a constant independent of Rw and solely a function of pore geometry (the Archie equation I).

### What is the effect of on the volume of a gas?

Boyle ’s law Decreasing the volume of a gas increases the pressure of the gas. An example of this is when a gas is trapped in a cylinder by a piston. If the piston is pushed in, the gas particles will have less room to move as the volume the gas occupies has been decreased.

### What is the formula for volume of gas?

– P= pressure, – V= volume, – N= number of gas molecules, – k= Boltzmann constant, 1.381×10 −23 J·K −1 in SI units, and – T= temperature (K)

What is the gas volume formula?

– The volume occupied by a gas. – The pressure exerted by a gas on the walls of its container. – The absolute temperature of the gas. – The amount of gaseous substance (or) the number of moles of gas.

#### What factor affects the pressure of an enclosed gas?

Boyle’s Law. According to Boyle’s law,the volume of the gas is inversely related to pressure when the amount of gas is fixed at a constant temperature.

• Charles’s Law. According to Charles’s law,the volume of the gas with a fixed mass is directly proportional to the temperature.
• Gay-Lussac’s Law.
