WitrynaImmiscible gas injection requires in situ oil to be greater than 40 °API, below which immiscible gas injection cannot make the oil mobile enough and miscible gas injection should be adopted. Since two distinct phases exist in immiscible flooding, fingering and channeling, similar to water flooding, could occur. Witryna8.3.1 Gas phase 8.3.1.1 Miscible water alternating gas injection. WAG injections can be difficult to identify between miscible and immiscible. The miscible WAG process aims to reduce or remove the interfacial tension (IFT) between the oil and the displacing phase (the miscible gas) during the EOR process [16].A continuous slug of gas is injected …
