Oil displacement efficiency

Created by Arthur Aslanyan (Nafta College), last modified on Aug 06, 2018

$\begin{array}{l}\displaystyle E_D (s_w) = \frac{s_w - s_{wi}}{1-s_{wi}}\end{array}$

The maximum oil displacement efficiency is given by:

$\begin{array}{l}\displaystyle E_D = \frac{1 - s_{or} - s_{wi}}{1-s_{wi}}\end{array}$

where $\begin{array}{l}s_{or}\end{array}$ – irreducible oil to water sweep.
