Determination of reasonable reserve/production ratio for oilfield and the influential factors;

A new method of research on injection-production pressure system and reasonable injection-production ratio

Methods to predict remaining recoverable reserves and reserve-production ratio of oil and gas fields;

Theory of structural reserve-production ratio and reserve-production ratio analysis of La-Sa-Xing reservoirs;

The remaining recoverable reserves and reserve-production ratio (RPR) are two important parameters of the development of oil and gas fields.

Lasaxing Oilfield attributes to various structural development oilfield,thus study on several development indexes variation rules,including water cut,declining rate,reserve/production ratio,remaining recoverable reserves and production ratio,the effects of various development index variation on the whole index are considered,in other words,which is structure analysis method study.

After many years experience in oilfield development, planning workers take it for granted that reserve/production ratio is closely related to decline rate.
