Frequently Asked Questions (FAQs)

What is the Bull Dog® Fishing Magnet used for?
Bull Dog Fishing Magnets are designed to recover metallic debris from the wellbore — including nuts, bolts, slips, wire, mill cuttings, and other steel objects. They're commonly used in cleanout and fishing operations where mechanical engagement tools aren't effective.
How does the Bull Dog® Fishing Magnet work?
The tool uses high-strength permanent magnets to attract and hold metal debris as it’s lowered into the well. The magnet face draws metallic objects into contact, where they stay attached until the tool is pulled to surface for recovery. No mechanical catch or circulation is required.
What sizes are available for Bull Dog Fishing Magnets?
Standard sizes range from 1" up to 20" O.D., in ½-inch increments. This allows operators to match the magnet to their casing or tubing size for maximum contact and retrieval performance. Custom sizes are available to suit non-standard or tight-hole operations.
When should I use a magnet instead of another fishing tool?
Use a fishing magnet when the debris is:
Loose and metallic (e.g., bolts, wire, shavings)
Too small for overshots or spears
Sitting in an open or horizontal wellbore section
At risk of compacting into a bird’s nest if disturbed
Can Bull Dog Fishing Magnets be customized for specific jobs?
Absolutely. Bull Dog can adjust the magnetic strength, OD/ID, connection type, and body length to match your job requirements. We can also build magnets for high-temp, sour service, or horizontal wells upon request.
