Estimation of Economic Recoverable Index for High Watercut Stage in Karamay Conglomerate Reservoir

Abstract

Abstract: This paper presents three methods for estimation of economic recoverable reserve, surplus economic recoverable reserveand economic recovery factor, i.e. watercut vs cumulative oil production curve, waterflood type curve and monthly oil productionvs time curve, which are based on the characteristics of Karamay high watercut conglomerate reservoir and domestic policy ofpresent finance and taxation.The typical case estimation shows that these methods are effective and feasible for obtaining aboveindices.

Key words: Karamay, conglomerate reservoir, high watercut stage, economy, recoverable reserve
