AMC BORE SEAL™ is a cellulose based product that is used to improve borehole stability by improving invasion control, seepage loss and other loss control situations.
It is available in three grades – (F)ine, (M)edium and (C)oarse. AMC BORE SEAL™ F fibres will matrix within the wall cake to form an impermeable thin skin on the filter bed resulting in minimal fluid invasion into the formation. AMC BORE SEAL™ M & C can be used as loss circulation additives when partial return or seepage loss is encountered.
Down the borehole, you can’t always predict when or how things will go wrong. AMC’s patent pending Borehole Optimisation System (AMC BOS™) anticipates fluid loss, lost circulation and unstable zones, even in the most difficult conditions – making operations smoother and more predictable.
AMC DRILL PAPER™ is a blend of variable sized particles of ground paper that is applicable for use in all water based drilling fluid systems used to cure lost circulation.
AMC PLUG™ is a polymer in granular form that absorbs up to 500 times its original volume in water. AMC PLUG™ is ideal for sealing zones of lost circulation and can also be used to reduce rod vibration in holes where lost returns are a problem.
AMC WALPLUG™ (F, M, C) is made from ground nut shells and is noncompressible, so it can be used in squeeze slurries as well as more conventional LCM applications. AMC WALPLUG™ is available in fine, medium and coarse grades.
MAGMA FIBER is a specially formulated extrusion of spun mineral fibre. The long, flexible fibres will reduce seepage and lost circulation by bridging and plugging off voids, fractures and all types of permeable formation.
