Collapsed Tubing Anchor Repair
While running a tapered 4.5 x 5.0 in. long string completion, a mechanical tubing anchor pre-set 4,000 ft prior to reaching the bottom. Only one slip on the tubing anchor set, which caused the ID of the 5 in. tool (4.044 in.) to collapse down to a 3.8 in. ID after weight was applied. The liner also failed a pressure test which halted the frac schedule.
