A well in 5,610 ft (1,710 m) in the Gulf of Mexico (GoM) required intervention after a loss in production. Baker Hughes, a GE company (BHGE), recommended the Mechanical Pipe Cutter™ (MPC™) electromechanical pipe-cutting tool in the 20,696-ft (6,308-m) deep well. The MPC reduces logistical and environmental constraints by providing precise, downhole pipe cutting without the use of ballistics or hazardous chemicals, reducing nonproductive time (NPT), risks, and overall intervention costs.

The operation involved running a mechanical tubing hanger through the 12° deviated borehole; cutting the 5½ in., 25% chrome (25 Cr) tubing at a depth of 18,750 ft (5,715 m); pulling the upper completions; and rerunning an upper completions assembly.

Challenges

  • Offshore recompletion well with a well depth of 20,696 ft, and a water depth of 5,610 ft
  • Cut depth of 18,750 ft in a 12° deviated borehole

Results

  • Performed the cut in 34 minutes on the first attempt
  • Eliminated a dress off run, reducing costly rig time
  • Recovered the entire tubing and upper completion safely from the well in a single trip
  • Deployed the MPC tool with a portable system and ran the tool on a competitor’s wireline
  • First 3¼-in. tool operation in the GoM for the operator
