SET® Openhole Liner Isolates Loss Zone; Ending NPT with No Loss of Casing Size!
An Operator in the Gulf of Mexico encountered severe loss circulation while drilling below 16 in. casing set at 4,980 ft. The SET OHL isolated the trouble zone, while providing a 14.028 in. post-expanded ID. The operator was able to run 13-5/8 in. conventional casing (semi-flush with 13.844 in. OD connections), through the expanded 13-3/8 in. SET liner without losing a casing size in the overall wellbore design. This combination of 13-5/8 in. semi-flush conventional casing being run through expanded 13-3/8 in. SET has proven to be a value adding solution.
