  • KOC turns a mutt into a thoroughbred

    M. Al-Mutawa and R. Kelkouli

    An old expression says, “It’s best to let sleeping dogs lie.” Kuwait Oil Company (KOC) could have walked away from its Sabriyah SA210 well and chalked it up to a bad investment, when it stopped flowing shortly after completion in 2004. Instead, the company tried a new technique to rejuvenate the failing well with good results. The SA210 was an open-hole completion, J-Type directional well. Kick-off point was at 6,264 ft (MD), and the well was landed at 8,376-ft MD (7,621-ft TVD), with a 1,337-ft stepout. A 7-in liner was run and cemented in place at an 8,162-ft MD (7,601-ft TVD). The 2,462-ft production section was drilled with a 6 1/8-in. bit to 10,838 ft (MD). Bottomhole pressure was about 3,093 psi, and temperature was 170°F. The target formation was the Mauddud Limestone, normally a prolific producer. It was therefore, puzzling to everyone when the SA210 failed to produce.
