multiple-contact miscibility

1. n. [Enhanced Oil Recovery]

A dynamic fluid-mixing process in which an injected gas exchanges components with in situ oil until the phases achieve a state of miscibility within the mixing zone of the flood front. In a vaporizing drive, light and intermediate components from the oil phase enter the gas phase. By contrast, in a condensing drive, intermediate components from the gas phase enter the oil phase. The process may be a combination of vaporizing and condensing drives.

Synonyms: dynamic miscibility

See: condensing drivevaporizing drive
