Novel Technique Used to Cut Eccentric Casing Strings

A new technique developed by Energy Fishing & Rental Services (EFRS) was used to successfully cut totally eccentric 5, 7, 10-3/4, and 16-in. strings in Gulf of Mexico well, with a single cutting tool. The technique was developed in response to a problem faced by an operator during a plug-and-abandonment operation.

Because all four casing strings were cemented together, conventional multi-step cutting, using graduated-size cutting tools and knives, was impossible. EFRS used a combination of specially fabricated cutter knives and a unique, EFRS-designed procedure that used the correct combination of pump pressure and torque monitoring to cut all four totally eccentric inner strings using a cutter that typically could not have been used in this application.

A job considered impossible was performed efficiently, with all strings cut and pulled. All four eccentric casing strings were cut using an EFRS 3Ĺ-in. OD two-blade internal hydraulic casing cutter. The quick visualization, development, and execution of specific procedures to complete an extremely difficult job has created a new option for effectively overcoming similar problems in P&A work.
