WebIn petroleum systems, we use the term first-contact miscibility pressure (FCMP) to define any pressure at which the injection gas and reservoir fluid mix on first contact (in any proportion), forming a single phase. The minimum first-contact miscibility pressure () is obtained from a swell test, defined as the maximum pressure on a p-x diagram ...

WebOct 3, 1971 · Processes in Class 1 are sometimes characterized as having first contact miscibility; one example of such a process is the propane slug process. There are two important types of Class 2 processes, the enriched gas-drive process and the high-pressure gas process. In the enriched gas-drive process the injected gas contains methane and ... Webmultiple-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.

WebAt a given pressure and temperature, first-contact (FC) miscibility refers to the process in which two fluids mix in all proportions – at any concentration of either fluid – such that the resulting mixture remains a … WebJun 4, 2015 · Phase diagrams of the types described here are often used to represent miscible gas-injection processes. The simplest form of miscibility is first contact miscibility. It occurs when a given gas is injected into oil at a temperature and pressure at which any mixture of the oil and gas result in a single-phase fluid.
