Synonym: Gasflood Recovery = Gasflooding
Motivation = maintain formation pressure at sweep interface with gas in case of high water mobility
\frac{k_{rw}}{\mu_w} \gg \frac{k_{ro}}{\mu_o} makes waterflood inefficient.
| (1) | E_{Dog} = 1- \frac{V_{o, \ LEFT}}{V_{o, \ INITITAL}} = \frac{1-s_{wi}-s_{org}}{1-s_{wi}} |
where s_{wi} – initial water in oil pay, s_{org} – residual oil to gas sweep.
