GVHD II-MagTM

The GVHD II-MagTM is a robust, non-rotating wellbore clean-up magnet suitable for all downhole conditions and with robust, high performance features.

Run separately or as part of a comprehensive wellbore clean-up, the GVHD II-MagTM is designed to effectively remove ferrous metal debris from the wellbore.

The external ribs with integral magnets are arranged to channel fluid through clearly defined flow paths. The magnet inserts capture metal debris and retain them securely for removal at surface.

The alloy bronze bearings feature both axial and radial elements to allow extended rotation in harsh environments, preventing tool and casing wear.

The GVHD II-MagTM can be run alone or as part of a comprehensive wellbore clean-up BHA. It is typically run in a BHA above a casing scraper and brushes as it complements the hard scraping action to remove rust and ferrous debris from the wellbore.

GVHD II-MagTM is centered in the casing by the integral GVHD II-MagTM sleeve with interchangeable non-rotating Centralizers. These guide and centralize the tool while allowing extended rotation without casing or tools wear.

While running in the hole or circulating, the well fluid passes along channels between the magnetized ribs capturing ferrous debris.

The ribs also prevent debris from being knocked off while circulating or tripping.

The robust tool design, non-rotating centralizers and large debris capacity allow milling of packers, or clean-up of casing windows, to be simple and efficient. 

The bronze alloy bearings have both axial and radial elements to allow extended rotation of the string without damage or wear to the tool or the casing.
