WebJul 29, 2024 · 2.4.3.1 First-Contact Miscibility (FCM) Miscibility is a dynamic process and may occur at the first contact between phases, known as first-contact miscibility (FCM). In operation of this process, a relatively small primary slug is injected which is miscible with reservoir fluid. Then a larger and less expensive slug is followed the primary slug. WebMultiple Contact Miscibility Processes An injected solvent which is not miscible with oil at first contact may achieve miscibility during multiple contacts and mass transfer between reservoir oil and injected fluid. oncologists in spokane waWebThere are two types of miscibility that can occur between resident oil and injected gas.
