WOR vs Recovery plot

Created by Arthur Aslanyan (Nafta College), last modified on Jun 15, 2023

Semi-log plot of WOR against cumulative oil production $\begin{array}{l}Q_O\end{array}$ or Oil Recovery Factor (RFO) (see Fig. 1).

Fig. 1. WOR (logarithmic vertical axis) vs RFO (linear horizontal axis)

Linear trend of WOR towards WOR Cut-off sill (usually 49) is pointing at Estimated Ultimate Oil Recovery (EUOR).
