It does not include water flooding, unless the water flooding is used as an element of one of the qualifying tertiary recovery techniques described in this subsection, or immiscible natural gas injection.

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. WitrynaConclusions •Oil Type: •Immiscible CO 2 combined EOR and storage is effective in 40 API and 30 API oil reservoirs •Injection Rate: •Lower injection rates lead to more efficient oil production per unit CO 2 due to increased water and oil displacement •Production Well Shut-Off: •Ignoring oil production at some stage may improve objective
