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
