An NOC well was drilled and cased with a 7-in. CSG to an intermediate depth. Additionally, a 4½-in. liner was run on the drill pipe to the total depth of the well. The liner was cemented, and with a failed attempt to set a liner top packer, the drill pipe became stuck.

A series of technologies where used for several days to free the drill pipe. A freepoint tool was run to determine the stuck point. The tool encountered obstructions and a blind backoff of the drill pipe had to be performed. Freepoint tools were deployed again to determine where the free pipe was located.

The client then sought Baker Hughes to handle the process of freeing the drill pipe.

The Mechanical Pipe Cutter™ (MPC™) tool was deployed to cut the pipe above the stuck point. Several cuts had to be made due to the condition of the pipe and the cement in the hole. The MPC successfully cut the pipe at three different depths, allowing the severed pipe to be retrieved effectively.

The indication of positive cut as well as the ability to control the depth of cut, where critical factors in this operation as free point indication was very difficult to achieve. The client was very pleased with the timely operations and the results achieved after having encountered other unsuccessful methods to free the stuck drill pipe.
