A Simple Method for Production Decline Analysis

Abstract

Abstract: Based 011 lthte allalyses of Arps production deeline law and changes of remainling resorve-productiot ralio. a simple and convenient letod for estimating de:line factors and recovcrable reservcs during lecline period in d11V oilfield was presented. It is indicatedl thal this ('an be dble lo meet the requirements of actual production. Using this methud. such unreasonable cuses as estinated recoverable reserves are less thal acuinulative producliol or decline factors are bigger than 1, henve causing estimation of the reasonable reservcs lo be invalid ur iusignificanl. ("ould be voidable. Furthermore. the classification of production decline lypes arnd lange of deline faclor values have been approached in this paper.
