Low-Friction /Anti-Corrosion Drill Pipe

DESCRIPTION / APPLICATION

Low-friction drill pipe is a revolutionary product that is made available by the electro-deposition of a corrosion-resistant, low-friction, wear-resistant layer bonded at the atomic level onto the surface of conventional drill pipe.This cobalt-based formula has been utilized extensively in the aerospace industry by its developer, Honeywell. The electro-depositional layer does not have any holes or microcracks, as seen in most common alternatives, and it has a high bonding strength. This new product is a game changer for directional drilling and paradigm shift in the approach of designing and implementation of deviated wells.

OPERATION

When the low-friction drill pipe is used, the existing slips and drill pipe tongs may need to be replaced with new proprietary low-friction counterparts.This solution offers proper makeup to achieve the smallest surface resistance downhole.

CHARACTERISTICS

1. Anti-Corrosion: corrosion-resistant drill pipes can effectively prevent the corrosion caused by acidic and corrosive media with chloride ions
2. Wear Resistance: wear-resistant drill pipe is more durable and has a longer working life
3. Drag Reduction: provides higher rates of penetration and lowers drilling costs

FEATURES/BENEFITS

1. When POOH, the pick-up weights associated with the drillstring will be reduced
2. When RIH, the drag attributed to slack-off weight decreases significantly
3. When drilling directional wells, the torque and drag models are altered as a lower coefficient of friction helps mitigate high-dogleg and extended-reach problems
4. Better WOB transfer in horizontal wells due to decreased drag
5. Electroplating can be applied to both ID and OD
6. Suitable for various H2S, CO2 and other corrosive environments
7. Greatly increased service life of conventional drill pipes
