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

Therefore, the **standing bubble point parameter, a** is **-0.68574**.
