Luxembourg headquartered Neo Oiltools launched its downhole torque management tool, NeoTork.
NeoTork automatically manages torque generated from the drill bit and mitigates axial and torsional vibrations.
The system has been through extensive lab and comparative field tests in its development phase. In the results, vertical vibration dropped by a factor of four and stalling virtually disappeared even with heavy loading (the drill string without NeoTork stalled 15 times). The BHA with NeoTork in place achieved a 40% improvement in the rate of penetration.
The technology has been designed to ensure that once downhole torque exceeds the preset limit, a system of disc springs and steel cables automatically contracts to reduce the bit depth of cut. The excess torque ‘stored’ in the system is slowly released as the drilling structure drills off. Crucially, the bit remains engaged in the formation at all times so drilling is not interrupted.
NeoTork can be used in a number of industry applications on both drilling rigs, or with coiled tubing in any operation that requires milling, drilling or cutting of material using rotation. It can also be used in specialized operations such as coring, hole enlargement, directional drilling, casing milling and well intervention.
The company is now looking to agree commercial applications for its coiled tubing variant (sizes available from 2 1/8 up to 3 1/2 inch). Tools for larger hole sizes, as well as conventional drilling applications, are due to be available from late Q3 2015 for testing.
