Case Study: Kuwait Oil Company boosts oil production and reduces water cut with SLB downhole water sink technology

First Downhole Water Sink with ESP Improves Oil Recovery and Production Rates for KOC

SLB worked with Kuwait Oil Company to address high water production and coning in a naturally flowing oil well completed near the oil/water contact in a water-driven reservoir. The challenge was to improve oil recovery while reducing water cut and limiting the burden on surface water handling facilities.

SLB installed downhole water sink (DWS) technology using a shrouded ESP to draw water away from the oil zone and reinject it into a lower aquifer. The pilot increased oil production by 15%, reduced water cut from 74% to 70%, extended natural-flow production without artificial lift, and lowered water treatment load on surface facilities.
