How does CR 650 work?

CR-650 forms a protective polymer film on the drill core and on the walls of the bore hole. This polymer film reduces water invasion into hydratable and dispersive clays and shales. CR-650 is also very effective for stabilizing loose, friable sand formations.

How do you mix CR 650?

0.5 – 0.75kg/m3 – Add to Fresh Water Under normal drilling conditions CR-650 should be mixed by adding slowly through a jet tunnel or high speed stirrer. CR-650 forms a protective polymer film on the drill core and on the walls of the bore hole. This polymer film reduces water invasion into hydratable and dispersive clays and shales.

What is AMC CR 650tm?

he formation. AMC CR 650TM forms a protective polymer film on the drill pipe and bit as well as on the walls of the bore hole which helps to provide lubrication when drilling in troubleso e formations. It is ideally suited for use in horizontal directional drilling, water well, mining and tunnelling

Can CR 650 be used as a mud system?

CR-650 can be used as a single product, low solids mud system, or it can be combined with AUS-GEL/AUSTROL to form a complete mud system. Effective – mixes rapidly in fresh to brackish water with minimum shear. Economical – 92% active. Provides excellent viscosity at a minimum concentration.
