What does your fluid need?

Easy-Bore™ extends a bentonite slurry: added to Pileman® at 50 kg per m³, the gel lifts the Marsh viscosity from 48″ to 100″ and beyond. It coats and encapsulates cuttings on shale and reactive clays, prevents bit balling and reduces drill torque.
Supplied as a gel, Easy-Bore™ dissolves fast in a bentonite suspension, without the fish-eyes that powder PHPA forms, and is compatible with most drilling fluid products, biopolymers, PAC or CMC. Fresh water only, treated with soda ash light.
AM-PAC™ is a fluid-loss and filtration controller, and a minimal viscosifier, at 100 to 500 g per m³ of bentonite slurry. It is effective in saline water, over a wide pH range, and is not susceptible to a variety of bacterial attack.
Foam-Drill™ makes a stable foam at low concentration, typically 10 kg per m³, that carries the cuttings out and cools the bit: for air, reverse circulation, rock, water-well and mining work, and in loss-circulation zones.
Easy-Bore™ and Foam-Drill™ work together on reactive clay: the gel coats the clay and the foam carries it out, so it doesn't ball on the cutting head in HDD or microtunnelling. In our own test, a reactive clay ball broke down in fresh water within 15 minutes and stayed whole in the Easy-Bore™ + Foam-Drill™ mix.

Own plant, Domjur
The polymers, cellulose and foam in every pail and drum are made at our own plant at Domjur, Howrah.
Viscosity takes Easy-Bore™. Fluid-loss control takes AM-PAC™. Air and foam drilling takes Foam-Drill™.

Easy-Bore™ to thicken a bentonite slurry and protect against shale and reactive clay, in fresh water. AM-PAC™ to control fluid loss, in fresh or salt water. Foam-Drill™ to make drilling foam for air, rock, water-well and mining work, in fresh, brackish or seawater. Not sure? Send us your drilling fluid details and the technical desk replies within 1 working day.
It thickens it, while the fluid loss stays the same. How much to add depends on your bentonite, ground and water: send us your mud programme.
No. Use it in fresh water only, treated with soda ash light; it is not designed for chloride or hard water of any kind. AM-PAC™ is effective in saline water, and Foam-Drill™ works with all types of make-up water, including hard, brackish and seawater.
100 to 500 g per m³ of bentonite slurry, depending on drilling conditions. It controls fluid loss, adds a little viscosity, works across a wide pH range and helps hold back reactive clay and shale.
About 10 kg per m³ in fresh water; with heavy water influx, raise the concentration and lower the injection rate. It is used for air drilling, reverse circulation, rock drilling, water wells, mining and EPB tunnel face support, and, with AM-PAC™ or Easy-Bore™ gel, as a stiff foam for sticky clay and shale.
Easy-Bore™ gel ships in 25 kg pails, AM-PAC™ in 25 kg bags, and Foam-Drill™ in 210-litre barrels.
Amrfeo, since 1994. All three are made by us at our polymer plant at Domjur, Howrah, West Bengal, under an ISO 9001:2015 quality system; our bentonite, Pileman® included, is mined and processed at Bhuj, Kutch. We are a Star Export House recognised by the Government of India, and export through Mundra and Kandla.
