Houston, Texas (Sept. 15, 2009) – The MAGNOSTAR* high-capacity magnet tool from M-I SWACO Wellbore Productivity* provides operators with a single piece tool specifically designed for high torque strings, but that can also be used in conventional workstrings. The tool provides superior magnetic surface area for high volume ferrous debris extraction when circulation is not enough for wellbore clean-up.
The MAGNOSTAR tool is run in the well on the workstring with other wellbore clean-up tools for a variety of applications, including: displacements, post perforating, prefracturing, multi-zone completions, milling, burning, fishing and smart completions. It can be run whenever there is a potential for significant ferrous debris in the wellbore.
To address a client’s needs in Norway, the 7 in (17.78 cm) MAGNOSTAR tool was run-in-hole with several other M-I SWACO Wellbore Productivity tools in the clean-up string. The tool collected 13.2 lbs (6kg) of ferrous metal debris, most of which was small in size although large slivers up to 6 in (15.2 cm) in length were recovered.
The MAGNOSTAR magnet is a single piece mandrel with no internal connections. With its high strength, rare earth magnets, rated to 350° F (177° C), it can remove up to 200 lbs (91 kg) of ferrous material. It is available in common casing/lining sizes and weights – from 13 ⅜ in to 7 in and has a casing compatible facing material to minimize casing wear.
The tool is available through the M-I SWACO Wellbore Productivity group.
M-I SWACO, which is based in Houston, TX and jointly owned 60% by Smith International, Inc. (NYSE, PSE:Sii) and 40% by Schlumberger Limited (NYSE:SLB), is a leading provider of a wide range of products and engineering services designed to deliver Drilling Solutions, Environmental Solutions, Wellbore Productivity and Production Technologies. The company is strategically located in more than 70 countries.
