Case Study: a large producing oil company restores oil production and reduces water cut with SLB CoilFLATE and AllSeal

CoilFLATE and Water-Shutoff Systems Restore 75 m3/d Oil Production in Wells

SLB worked with a large producing oil company in West Africa that had two horizontal wells shut in for more than 10 years because water cut exceeded 90%. The operator needed to restore production without permanently plugging the wells, and SLB used its AllSeal water and gas conformance service along with CoilFLATE coiled tubing through-tubing inflatable packers to address the problem.

SLB isolated the water-producing intervals with CoilFLATE packers and then placed OrganoSEAL organic crosslinked gel in well A and SqueezeCRETE remedial cement in well B to seal the leaks and block water breakthrough. Four months after treatment, water cut fell from 90% to 70% in well A and to 80% in well B, enabling the company to bring back oil production of about 75 m3/d and consider similar treatments for other wells.
