The image above represents the Vasquez-Beggs Gas Solubility.

To compute for the Vasquez-Beggs gas solubility, five essential parameters are needed and these parameters are **API Gravity (°API), Temperature (°Rankine) (T), Gas Gravity at Reference Separator Pressure (γ _{gs}), Gas Gravity at Actual Separator P_{sep}**

**and T**and

_{sep }(γ_{g})**Gas Solubility Parameter (C**

_{1}, C_{2}, C_{3}).The formula for calculating Vasquez-Beggs gas solubility:

R_{s} = C_{1} γ_{gs} γ_{g}^{C2} exp[C_{3}(^{°API }/ _{T})]

Where:

R_{s} = Vasquez-Beggs Gas Solubitity

°API = API Gravity

T = Temperature (°Rankine)

γ_{gs} = Gas Gravity at Reference Separator Pressure

γ_{g} = Gas Gravity at Actual Separator P_{sep} and T_{sep}

C_{1}, C_{2}, C_{3} = Gas Solubility Parameter

Let’s solve an example;

Find the Vasquez-Beggs gas solubility when the API Gravity is 24, Temperature is 180, gas gravity at reference separator pressure is 60, gas gravity at actual separator is 56, gas solubility parameter is 72, 66 and 45.

This implies that;

°API = API Gravity = 24

T = Temperature (°Rankine) = 180

γ_{gs} = Gas Gravity at Reference Separator Pressure = 60

γ_{g} = Gas Gravity at Actual Separator P_{sep} and T_{sep} = 56

C_{1}, C_{2}, C_{3} = Gas Solubility Parameter = 72, 66, 45

R_{s} = C_{1} γ_{gs} γ_{g}^{C2} exp[C_{3}(^{°API}/ _{T})]

R_{s} = 72 x 60 x 56^{66} exp[45(^{24}/ _{180})]

R_{s} = 72 x 60 x 56^{66} exp[45(0.133)]

R_{s} = 72 x 60 x 56^{66} exp[6]

R_{s} = 72 x 60 x 2.401e+115 exp[6]

R_{s} = 72 x 60 x 2.401e+115 x 403.428

R_{s} = 6.974e+119

Therefore, the **Vasquez-Beggs gas solubility** is **6.974e+119.**
