Recover debris that cannot be circulated out of the well

This line of specialized tools is designed to recover debris that cannot be circulated out of the well, either mechanically or magnetically. Usually, these tools are run as part of the main wellbore cleaning string. They can also be used in upper well cleaning or as "catching" devices during packer or whipstock retrieval.

Example of the volume and types of debris recovered using M-I SWACO debris management tools.
