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).Â
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.
