Systems and methods presented herein provide for well decommissioning in through-tubing applications. A carrier for well decommissioning in through-tubing applications, can comprise a perforating assembly that includes at least one of (1) gun charges, and (2) a mechanical cutting device. The carrier can also include a sensor package that determines geometry of tubulars installed in a wellbore, including eccentricity of the tubulars. The carrier can further include an orienting device that orients the carrier to control the perforating assembly. The carrier can also include a roller assembly that allows the carrier to move longitudinally and rotate around a central axis.
A carrier for well decommissioning in through-tubing applications, comprising:
The method of claim 9, wherein the orienting device is on an opposite side of the carrier from the perforating assembly.
The method of claim 9, wherein determining the geometry includes determining an eccentricity of the tubular.
The method of claim 9, wherein the carrier is attached to one of a slickline, wireline, and coiled tubing.
The method of claim 9, wherein the roller assembly of the carrier assists the carrier in traversing downward through the wellbore and around obstacles.
The method of claim 9, wherein the sensor assembly provides real-time monitoring information to the orienting device, and wherein the orienting device uses the real-time monitoring information to press the carrier against the tubular.
A non-transitory, computer-readable medium containing instructions for well decommissioning in through-tubing applications, the instructions causing a processor to execute stages comprising:
