CA 2271620

A debris collector to collect falling metallic debris within a borehole casing following a casing perforation process includes an elongate housing having opposite ends. One end of the housing is adapted to be coupled to a string of at least one perforating gun. A magnet assembly is disposed within the housing. The magnet assembly generates a generally evenly distributed magnetic field generally along the length of the housing to catch falling metallic debris. The magnet assembly includes a plurality of magnets each of which is separated by a pole of magnetizable material. Successive magnets are oriented to generate magnetic fields of opposite polarity. A centralizer collar is coupled to an opposite end of the housing to position the debris collector centrally within the casing.
