Many factors are involved in the selection of a profitable enhanced oil recovery process. However, the ability to achieve miscibility at low reservoir pressures increases the options available to the petroleum engineer and perhaps may permit the installation of a profitable oil recovery process. Reservoir temperatures usually range from ca 100 F up to more than 300 F depending primarily on the depth and the area located. In the application of an enhanced oil recovery program using miscible displacement, the goal usually is to achieve miscibility at the lowest pressure possible. Laboratory studies using CO/sub 2/ show that the miscibility pressure between a crude oil and carbon dioxide increases almost directly with a reservoir temperature.
