Fluid Property Behavior

Oil Bubble Point Pressure

In this section, I would like to make sure that you can easily describe the behavior of your oil bubble point pressure. Therefore, I will give you brief technical notes by answering three questions.
The behavior of oil bubble point pressure at any reservoir pressure
Behavior of the oil BP pressure versus pressure
Why the oil bubble point pressure is the first PVT property that you need to estimate for your reservoir fluids?
It’s good to know that almost any black oil PVT property tends to behave at pressures less than bubble point pressure, entirely different from the way it behaves at pressures greater than bubble point pressure. And that’s why you need to calculate the oil bubble point pressure at first. Moreover, almost all the black oil properties respond differently to the decrease in reservoir pressure.
What are the PVT properties that are affecting the value estimated for the oil bubble point pressure?
Actually, the oil bubble point pressure is completely independent of any other black oil PVT properties.
What are the PVT properties that depend on the value estimated for the oil bubble point pressure?
The solution gas-oil ratio is strongly dependent on the value estimated for the oil bubble point pressure.
