Schlumberger provides several solutions for recovering casing, drillpipe, coiled tubing, or tubing.
After the free point is determined, stuck drillpipe can be loosened by using an explosive backoff or cut with severing or colliding tools.
Well completions can be recovered by using mechanical, explosive, electrical, or chemical cutters. Tubing can be cut in several places, but usually above the packer so that the packer can be milled and fished.
Schlumberger uses reputable third-party providers for many pipe recovery and remedial services. Contact your Schlumberger representative for more information.
