Water→Oil Displacement Efficiency = EDow

Created by Arthur Aslanyan (Nafta College), last modified on Sep 25, 2021

Displacement Efficiency (ED) of oil in response to water sweep:

$\begin{array}{l}\displaystyle E_{Dow} = 1- \frac{V_{o, \ LEFT}}{V_{o, \ INITITAL}} = \frac{1-s_{wi}-s_{orw}}{1-s_{wi}}\end{array}$

where $\begin{array}{l}s_{wi}\end{array}$ – initial water in oil pay, $\begin{array}{l}s_{orw}\end{array}$ – residual oil to water sweep.
