HoD - Heart of Drilling - HoD AF
Particularly during ERD (Extended Reach Drilling), one of the main technical hurdles to the success of the well project is reducing torque and drag, controlling fluid circulation.
To avoid downtime or malfunction, friction needs to be minimized during the drilling operations
Drillmec HoD A-F is a technical solution represented by special anti-friction rings, which have an excellent wear resistance and a low friction coating layer to reduce friction between the drill string and the internal casing surface, ensuring maximum protection of casing surface and a reduction of stresses coming from the drill string to the top drive.
When needed, the HoD A-F rings can be directly integrated in each HoD CC subs. The combined use of the HoD CC and HoD A-F gives the operator the capability to increase the length of horizontal drilling phases, through better hole cleaning and reduced frictions in the well.
