ROTATING FLOW CONTROL HEADS

High Arctic's Rotating Flow Control Heads provide a safe and economical means of diverting the flow of pressured gas or fluid to a recovery system during underbalanced drilling applications. High Arctic's RFH offers an advantage not available from existing rotating flow diverters in the industry. The sealed bearing design eliminates the need for external cooling and lubrication, and is DNV certified to operate throughout the world. The body is a cast ductile design which meets all API design and performance specifications and can be used in H2S drilling applications.

It connects to the existing BOP stack, and forms a positive seal on the drill string. It safely diverts the flow from the wellbore to the recovery system, and allows drilling and stripping of the drill string with up to 21,000 kPa (3,000 psi) wellbore pressure.

The RFH consists of three components; The body, which connects to the top flange on the BOP stack; the bearing assembly which houses the Sealed bearing, and the sealing element. The RFH sealed bearing assembly is held in the body by the clamp, and is quickly removed for quick change out or replacement with the snubbing/logging adapter for snubbing or logging operations.

The RFH offers many advantages not available from existing Rotating Flow Control Heads in the Industry:

  • Patented Sealed Bearing design eliminates the need for external cooling or lubrication
  • DNV Certified worldwide
  • Body is a cast ductile design with H2S trim, and meets all API specs.
  • The RFH height ranges from just 1.02m (40.50 in.) to 1.10m (43.5 in.), and 66cm (26 in.) wide, allowing installation down through the rotary table on larger rigs.
