Motor Head Assembly (MHA)

Product Code: WBI PDS 0016

The Motorhead Assembly (MHA) combines three standard CT running string components, Dual Flapper Check Valves, Heavy Duty Hydraulic Disconnect and Dual Actuated Circulating Sub into a single compact tool. The MHA has a reduced overall length in comparison to individual tool components and offers an advantage where rig-up height is limit.

The Dual Flapper Check Valve provides the primary internal well control barrier within the Coiled Tubing bottom hole assembly during live well intervention operations. The check valves prevent the wellbore fluid and pressure from entering the CT string.

The C-Load Style Hydraulic Disconnect is an extremely robust, heavy duty, drop ball emergency release tool. It allows a stuck bottom hole assembly (BHA) to be detached at a pre-determined point. The unique grapple design of the C-Load is the key to the tools inherent strength.

The Dual Circulation Sub is a drop ball activated circulation device and also incorporates a secondary emergency rupture disc facility. In the event that the BHA becomes plugged the rupture disc can be burst by applying a pre-determined pressure to regain circulation allowing the activation ball(s) to be circulated to depth.

Features:

  • Short compact design.
