The LiMAR High Pressure Motorhead Assembly (MHA) is an evolution of the LiMAR MHA, designed to operate in the harshest of environments to a working pressure of 15,000 psi.
The MHA houses LiMAR Single Piece Double Flapper Check Valves, Hydraulic Disconnect and a Dual Circulation Sub in one combined unit. The user has the option of dressing the tool to permit circulation after dropping the ball but prior to disconnecting, a valuable feature in circumstances where the Coiled Tubing is stuck above the BHA.
TOOL APPLICATIONS:
- For use in the BHA directly below the CT connector
- To provide a double barrier from well pressure & contents
- Torque-thru hydraulic disconnect option for contingent release
- Integral dual circulating function for coil-to-tubing circulation
- For use in height restricted rig-ups
- Specifically designed for high pressure applications
OPERATIONAL APPLICATIONS:
- Fishing operations in conjunction with high impulse jars and impact hammers
- Milling operations in conjunction with hi-torque PDM motors
- Explosive perforating operations
- Abrasive perforating operations with availability of especially hardened MHA internals
- Packer setting operations in conjunction with Inflatable, Hydraulic & Explosive setting tools
- Acidising, Cementing & Stimulation operations
- High Temp / High Pressure operations
