1. n. [Enhanced Oil Recovery]
A graphical representation indicating phase behavior for variation of saturation pressure and injection gas concentration at a given temperature. The diagram indicates conditions for single-phase and two-phase behavior and, within the two-phase region, lines of constant volume fraction, termed quality lines. The diagram is constructed using swelling test saturation pressures and liquid volumes.
