The image above represents the MBAL gas solubility.

To compute for the MBAL gas solubility, four essential parameters are needed and these parameters are **Specific Gravity of Solution Gas (γ _{g}), Specific Gravity of Stock Tank Oil (γ_{o}), Oil FVF (B_{o})** and

**Oil Density (ρ**

_{o}).The formula for calculating MBAL gas solubility:

R_{s} = ^{Boρo – 62.4γo} / _{0.0136γ}_{g}

Where:

R_{s} = MBAL Gas Solubility

γ_{g} = Specific Gravity of Solution Gas

γ_{o} = Specific Gravity of Stock Tank Oil

B_{o} = Oil FVF

ρ_{o} = Oil Density

Let’s solve an example;

Given that specific gravity of solution gas is 9, specific gravity of stock tank oil is 13, oil FVF is 19 and oil density is 27. Find the MBAL gas solubility?

This implies that;

γ_{g} = Specific Gravity of Solution Gas = 9

γ_{o} = Specific Gravity of Stock Tank Oil = 13

B_{o} = Oil FVF = 19

ρ_{o} = Oil Density = 27

R_{s} = ^{Boρo – 62.4γo} / _{0.0136γ}_{g}

R_{s} = ^{19 x 27 – 62.4 x 13} / _{0.0136 x 9}

R_{s} = ^{513 – 811.19} / _{0.1224}

R_{s} = ^{-298.19} / _{0.1224}

R_{s} = -2436.27

Therefore, the **MBAL gas solubility** is **-2436.27.**
