n: 1. the temperature and pressure at which part of a liquid begins to convert to gas. For example, if a certain volume of liquid is held at constant pressure, but its temperature is increased, a point is reached when bubbles of gas be- gin to form in the liquid. That is the bubble point. Similarly, if a certain volume of liquid is held at a constant temperature but the pressure is reduced, the point at which gas begins to form is the bubble point. Compare dew point. 2. the temperature and pressure at which gas, held in solution in crude oil, breaks out of solution as free gas.

the pressure at which gas begins to break out of an under saturated oil and form a free gas phase in the matrix or a gas cap.
