Abstract
A wellbore magnet tool including a plurality of magnets positioned about an outer circumference of the wellbore magnet tool; a plurality of sensors, including: a first sensor proximal one or more of the plurality of magnets; and a second sensor positioned downhole from the first sensor, and an electronics board. The first sensor and the second sensor are electronically connected with the electronics board, and the first sensor and the second sensor detect changes in a magnetic field proximate thereto, which changes result from debris collection by the wellbore magnet tool.

(canceled)
The wellbore magnet tool of claim 10 further comprising a chassis, wherein the chassis is substantially cylindrical, and is positioned within an interior flow bore of the wellbore magnet tool, and wherein the first sensor, the second sensor, and/or the electronics board are connected to the chassis.
A wellbore magnet tool comprising:
- a plurality of magnets positioned about an outer circumference of the wellbore magnet tool;
- a plurality of sensors, including:
- a first sensor proximal one or more of the plurality of magnets;
- and a second sensor positioned downhole from the first sensor and proximal one or more other of the plurality magnets;
- and
- an electronics board;
- wherein the first sensor and the second sensor are electronically connected with the electronics board, wherein the first sensor and the second sensor detect changes in a magnetic field proximate thereto, which changes result from debris collection by the wellbore magnet tool, and wherein the first sensor, the second sensor, or both are positioned within a cylindrical wall of the wellbore magnet tool, proximal one or more of the plurality of magnets.
The wellbore magnet tool of claim 10, wherein the plurality of magnets are distributed about the outer circumference of the wellbore magnet tool in a plurality of magnetic areas, each magnetic area of the plurality of magnetic areas comprising one or more of the plurality of magnets, such that a plurality of non-magnetic areas are provided, with one of the non-magnetic areas distributed about the outer circumference of the wellbore magnet tool between each pair of the magnetic areas of the plurality of magnetic areas.
The wellbore magnet tool of claim 10, wherein the first sensor is positioned proximal a first end of the wellbore magnet tool and the second sensor is positioned proximal a second end of the wellbore magnet tool.
The wellbore magnet tool of claim 10, wherein the plurality of sensors comprises one or more additional sensors in addition to the first sensor and the second sensor, wherein the one or more additional sensors are electronically connected with the electronics board, and wherein the one or more additional sensors are configured to detect changes in a magnetic field proximate thereto, which changes result from debris collection by the wellbore magnet tool.
The wellbore magnet tool of claim 10, wherein the first sensor, the second sensor, or both directly detect Gauss readings or comprise magnetometers.
A wellbore magnet tool comprising:
- a plurality of magnets positioned about an outer circumference of the wellbore magnet tool;
- a plurality of sensors, including:
- a first sensor proximal one or more of the plurality of magnets;
- and a second sensor positioned downhole from the first sensor and proximal one or more other of the plurality magnets;
- and
- an electronics board;
- wherein the first sensor and the second sensor are electronically connected with the electronics board, and wherein the first sensor and the second sensor detect changes in a magnetic field proximate thereto, which changes result from debris collection by the wellbore magnet tool, wherein the changes in the magnetic field detected by the first sensor, the second sensor, or both can be utilized to determine, substantially in real time, if a debris collection capacity of the wellbore magnet tool has been reached or exceeded.
A method comprising:
- removably inserting a chassis into a flow bore of a wellbore magnet tool, wherein the wellbore magnet tool comprises a plurality of magnets positioned about an outer circumference of the wellbore magnet tool, wherein the chassis is substantially cylindrical, and wherein the chassis comprises a plurality of sensors and an electronics board positioned on an inside surface of the chassis, wherein the plurality of sensors include:
- at least a first sensor proximal one or more of the plurality of magnets;
- and a second sensor positioned downhole from the first sensor and proximal one or more other of the plurality magnets, and wherein the first sensor and the second sensor detect changes in a magnetic field proximate thereto, which changes result from debris collection by the wellbore magnet tool;
- positioning the wellbore magnet tool downhole in a wellbore in conjunction with a bottom hole assembly (BHA) utilized during a milling operation;
- collecting debris with the wellbore magnet tool during and/or subsequent the milling operation, wherein at least a portion of the debris is produced by the milling operation;
- and
- monitoring a debris collection capacity of the wellbore magnet tool during the collecting of the debris with the wellbore magnet tool, substantially in real time, by monitoring changes in the magnetic fields detected by the plurality of sensors.
