Enhanced recovery

EOR-Feasibility Study for a Large Carbonate Field in Kuwait

This study provides technical analysis of the viability of enhanced-oil-recovery (EOR) processes; the results indicate the potential for significant improvement in recovery efficiency over continued waterflooding.

This paper presents the results of reservoir simulations for the Mauddud reservoir in the Sabiriyah field (SAMA) in Kuwait, which is a high-temperature and high-salinity carbonate reservoir. The subject reservoir has been under pattern waterflood. Many wells experienced water breakthrough with considerable increase in water cut because of high reservoir heterogeneity and adverse mobility ratio. This study provides technical analysis of the viability of enhanced-oil-recovery (EOR) processes; the results indicate the potential for significant improvement in recovery efficiency over continued waterflooding.

Introduction

SAMA is a giant carbonate oil reservoir covering more than 200 km2 in northern Kuwait.
