SET® Openhole Liner Isolates Loss Zone; Ending NPT with No Loss of Casing Size!

Summary:

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.
