5.2.6 India’s Reserve Replacement Ratio (RRR) & Reserves to Production ratio (R/P)

Reserves Replacement Ratio (RRR) for a particular year in following manner:
RRR = [(Reserves accreted) / (total production)] during a FY

Change in EUR (Production+ reserves) denotes reserves accretion (+ve/-ve) during a financial year.

The Reserves-to-Production ratio (R/P) is an estimate of the number of years oil and gas reserves
will continue to produce based on current production rates. It does not account for future reserve
accretion; hence it tends to increase with the time.

R/P = [total reserves / total production during a FY] years
