Percentage of total hydrocarbon reserves recovered by a given time moment :
{\rm RF}(t) = \frac{{ \rm V_{recovered \ reserves}}(t)}{{\rm V_{total \ reserves}}} |
It always ranges and is related to Depletion Factor (DF) as:
{\rm RF} (t) = {\rm EUR} \cdot {\rm DF}(t) |
where EUR is Estimated Ultimate Recovery.
