In Decline Curve Analysis the R/P equation takes form:

R/P is RPR is measured in time units and is usually presented in years.
For the green fields the RPRthe R/P assumes the ratio of initial recoverable reserves over the initial production rate.
Although RPRR/P is expressed in time units it does not represent the actual actual expected lifetime of the field because production rate is not constant over time.
Usually production rate is declining thus leading to a much longer production time than estimated by RPRR/P.
But in many other cases the initial production rate of the green field is being increased over time due to increase in drilling and advanced completions which lead leads to contraction if of the field lifetime comparing to RPR estimate.to R/P estimate.
The R/P is closely related to Recovery Pace
and in case of Exponential Production Decline they simply match: LaTeX Math Inline body \tau
and stay constant over time. LaTeX Math Inline body --uriencoded--\mathrm%7BR/P%7D \equiv \tau
