Carbon Dioxide (CO2) Miscible Flooding in Tight Oil Reservoirs…
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 ... WebFeb 1, 2024 · This paper gives a critical review of miscibility-measurement techniques published in the open literature along with recommendations and lessons learned. Many of these published methods violate the inherent assumptions for multicontact miscibility (MCM). The confusion often arises from a failure to distinguish between first-contact … phil wickham greenville sc

WebFirst contact miscibility can be achieved for highly rich gas, or at very high pressure for lean gas. As Figure 5‑14 shows, higher-molecular-weight hydrocarbons, such as propane or LPG, are miscible with crude oil, at most reservoir conditions. Reservoir porous medium … WebMinimum miscibility enrichment or minimum miscibility concentration, the minimum quantity of additional components, such as intermediate-chain gases or CO2, that … 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. phil wickham god of revival
