Cricondentherm can be defined as the maximum temperature at which liquids and vapor can coexist.
At temperatures higher than cricondentherm only one phase occurs at any pressure. The liquid-vapor boundary terminates at a critical point with a critical temperature and critical pressure.
At temperatures above the critical temperature, dewpoints are observed. At temperatures below the critical temperature, the mix will split into two phases at the bubblepoint pressure.
Trenchlesspedia Explains Cricondentherm
When the reservoir temperature exceeds the cricondentherm in a gas well, only dry gas will exist in the reservoir throughout production.
If the reservoir temperature is below the cricondentherm, retrograde condensation occurs where oil condenses with decreasing rather than increasing pressure. In dewpoint reservoirs, the reservoir temperature lies between the critical temperature and the cricondentherm for the reservoir fluid.
In bubblepoint reservoirs, the temperature is less than the critical temperature of the reservoir fluid.
