How to Calculate and Solve for Standing Bubble Point Parameter | The Calculator Encyclopedia

The image above represents standing bubble point parameter.

To compute for the standing bubble point parameter, two essential parameters are needed and these parameters are API Gravity (°API) and Temperature (°Rankine) (T).

The formula for calculating standing bubble point parameter:

a = [0.00091(T – 460)] – [0.0125(°API)]

Where:

a = Standing Bubble Point Parameter, a
°API = API Gravity
T = Temperature (°Rankine)

Let’s solve an example;
Find the standing bubble point parameter when API Gravity is 32 and the temperature is 146.

This implies that:

°API = API Gravity = 32
T = Temperature (°Rankine) = 146

a = [0.00091(T – 460)] – [0.0125(°API)]
a = [0.00091(146 – 460)] – [0.0125(32)]
a = [0.00091(-314)] – [0.0125(32)]
a = [-0.28574] – [0.0125(32)]
a = [-0.28574] – [0.4]
a = -0.68574

How to Calculate and Solve for Standing Bubble Point | The Calculator Encyclopedia

The image above represents standing bubble point.

To compute for the standing bubble point, three essential parameters are needed and these parameters are Specific Gravity of Solution Gas (γg), Bubble Point Pressure (Pb) and Standing Bubble Point Parameter (a).

The formula for calculating the standing bubble point:

Rs = 18.2[((Pb / γg)0.83 x 10a) – 1.4]

Where:

Rs = Standing Bubble Point

This implies that;

γg = Specific Gravity of Solution Gas = 24
Pb = Bubble Point Pressure = 70
a = Standing Bubble Point Parameter = 45

Rs = 18.2[((Pb / γg)0.83 x 10a) – 1.4]
Rs = 18.2[((70 / 24)0.83 x 1045) – 1.4]
Rs = 18.2[((2.916)0.83 x 1045) – 1.4]
Rs = 18.2[(2.43 x 1045) – 1.4]
Rs = 18.2[2.431e+45 – 1.4]
Rs = 18.2[2.431e+45]
Rs = 4.425e+46

Therefore, the standing bubble point is 4.425e+46.
