Reserves to production ratios and present value relationships

摘要

Reserves to production ratio (R/P) is equivalent to the inverse of an exponential decline rate which is commonly used to forecast production rates. For a tank type gas reservoir, adding wells will incrase the pool's producing rate and reduce the reserves life and R/P. Therefore, R/P indirectly represents the amount of deveopment. For this analysis the optimum R/P0 is the value which results in the highest present value.
