The image above represents petrosky-farshad gas solubility.

To compute for the petrosky-farshad gas solubility, three essential parameters are needed and these parameters are **gas specific gravity (γ _{g}), petrosky-farshad gas solubility parameter (x)** and

**pressure (P).**

The formula for calculating the petrosky-farshad gas solubility:

R_{s} = [(^{P}/_{112.727} + 12.340)γ_{g}^{0.8439} 10^{x}]^{1.7384}

Where:

R_{s} = Petrosky-Farshad Gas Solubility

γ_{g} = Gas Specific Gravity

x = Petrosky-Farshad Gas Solubility Parameter

P = Pressure

Let’s solve an example;

Find the petrosky-farshad gas solubility when the gas specific gravity is 16, the petrosky-farshad gas solubility parameter is 22 and the pressure is 80.

This implies that;

γ_{g} = Gas Specific Gravity = 16

x = Petrosky-Farshad Gas Solubility Parameter = 22

P = Pressure = 80

R_{s} = [(^{P}/_{112.727} + 12.340)γ_{g}^{0.8439} 10^{x}]^{1.7384}

R_{s} = [(^{80}/_{112.727} + 12.340)16^{0.8439} x 10^{22}]^{1.9384}

R_{s} = [(0.709 + 12.340)16^{0.8439} x 10^{22}]^{1.9384}

R_{s} = [(13.049)16^{0.8439} x 10^{22}]^{1.9384}

R_{s} = [(13.049)10.379 x 10^{22}]^{1.9384}

R_{s} = [1.354e+24]^{1.9384}

R_{s} = 8.925e+41

Therefore, the **Petrosky-Farshad** gas solubility is **8.925e+41**.
