AGE Latching Screen Seal M-Packers

For naturally gravel packed water bore designs, AGE offers M-Packers as a superior alternative to the old K-rubber method to provide a permanent annulus seal between the telescoped screen riser and bore casing. While K-rubbers are at best glued and secured with Band-It straps, M-Packers are vulcanised directly to the riser pipe to ensure a robust bonding interface

The installation of M-Packer telescoped screen designs has seen many methods being used; j-latch installation, grab packers and left handed running tools, however each method to date have significant drawbacks (download Latching M-Packer Advantages for an in-depth comparison). 

AGE highlighted the need for improvement to install telescoped screened bores and designed/manufactured the AGE Latching Screen Seal M-Packers.

The latching system tool is run on drill rods and incorporates latching lugs that sit inside a recepticle within the M-Packer riser. Once at desired setting depth the drill string is pressurised to disengage from the screen riser.

Latching M-Packer Tool Features:

• Latch lugs are not effected by screen weight or rig pull back loads and can only be disengaged via pressure actuation on drill pipe
• Crossflow wash ports to negate hole swab during installation
• Positive surface indication of disengagement via pressure drop and flow through tool
• Hole de-mud can occur straight after setting tool disengages
• Hole can be airlifted by pumping air through the tool
• Tool can be quickly re-set on site for multiple screen installations

AGE M-Packers are available in a large range of sizes and materials, with a rubber sealing diameter machined specifically to order.

All water bore equipment is manufactured from stainless steel materials and potable water grade rubber compounds compliant to AS/NZS:4020.
