The second generation LiMAR Motorhead Assembly (MHA) is a technically enhanced version of the original LiMAR MHA, offering not only an increased pressure rating but a number of technical enhancements over the standard product.
The MHA houses LiMAR Single Piece Double Flapper Check Valves, Hydraulic Disconnect and a Dual Circulation Sub in one combined unit. This considerably shortens the overall length of the BHA and allows rig-up in situations where riser height is restricted.
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
DESIGN FEATURES & BENEFITS:
- Single piece cartridge type Double Flapper Check Valve safety system
- Superior torque rating
- High tensile and compressive strength rating
- Optional flow paths during disconnecting
- 10,000 psi Safe Working Pressure
- Drop Ball operated release and circulating feature with maximised flo area
- Benoil type rupture disc fitted as standard
- Disconnect Sub fitted with standard GS type internal fish neck profile
- Selected components QPQ treated
- Hexagonal flats for safe make-up & break-out
- Connection options to suit customer requirements
- Corrosion resistant materials
