## How to Calculate and Solve for Marhoun’s Gas Solubility in a Fluid | The Calculator Encyclopedia

The image above represents marhoun’s gas solubility.

To compute for the marhoun’s gas solubility, four essential parameters are needed and these parameters are Gas Specific Gravity (γg), Temperature (°Rankine) (T), Pressure (P) and Stock Tank Oil Gravity (γo).

The formula for calculating the marhoun’s gas solubility:

Rs = [a γgb γoc Td P]e

Where:

Rs = Marhoun’s Gas Solubility
a = 185.843208
b = 1.877840
c = -3.1437
d = -1.32657
e = 1.398441
γg = Gas Specific Gravity
T = Temperature (°Rankine)
P = Pressure
γo = Stock Tank Oil Gravity

Let’s solve an example;
Find the marhoun’s gas solubility when the gas specific gravity is 14, temperature is 80, pressure is 40 and the stock tank oil gravity is 24.

This implies that;

γg = Gas Specific Gravity = 14
T = Temperature (°Rankine) = 80
P = Pressure = 40
γo = Stock Tank Oil Gravity = 24

Rs = [a γgb γoc Td P]e
Rs = [185.843208 x 141.87784 x 24-3.1437 x 80-1.32657 x 40]1.398441
Rs = [185.843208 x 141.98 x 24-3.1437 x 80-1.32657 x 40]1.398441
Rs = [185.843208 x 141.98 x 0.0000458 x 80-1.32657 x 40]1.398441
Rs = [185.843208 x 141.98 x 0.0000458 x 0.00298 x 40]1.398441
Rs = [0.1445]1.398441
Rs = 0.0668

Therefore, the marhoun’s gas solubility is 0.0668.
