Percentage of recoverable hydrocarbon reserves recovered:

(1)	$\begin{array}{l}\displaystyle \rm DR = \frac{V_{recovered \ reserves}}{V_{recoverable \ reserves}}\end{array}$

It always ranges $\begin{array}{l}0 \leq {\rm DR} \leq 100 \%\end{array}$ and is related to Recovery Factor (RF) as:

(2)	$\begin{array}{l}\displaystyle \rm DR = \frac{RF}{EUR}\end{array}$

where EUR is Estimated Ultimate Recovery.
