The Use Of Slug Injection Of High Ph Water In The Recovery Of Viscous Crude Oils

Abstract: An experimental study has been con-ducted to investigate the effects on water flood oil recovery caused by the addition of sodium hydroxide to only a portion of the injected fluid. The results of inter-facial tension measurements between the viscous crude oil and water indicate that a low interfacial tension can be achieved at concentrations of sodium hydroxide varying from 0.1 to 7.0% by weight. The wide range of concentrations is a result of the signif-icant variation in water compositions.The results of dis… Show more
