POLYCOL

POLYCOL 60 S USE Viscosifier for drilling muds, easy to mix and very simple to use. Stabilize the hole walls, remove cuttings, increase core recovery in less consolidated formations. FORM Powder form product. Available in 500 grs, 1 Kg, 5 Kg, 25 Kg bags.

ADVANTAGES

• Little storage and low concentrations: 0,5 to 1,5 Kg/M³ of water, to obtain 40 to 90 sec marsh viscosity.
• Non toxic, non polluting polymer.
• Easy to mix.
• Avoid cake, there is no warping in water well drills.
• Reduce torque on inhole equipment.
• Improve drilling penetration rates.
• Better cuttings removal.
• Better core recovery in unconsolidated formations: when POLYCOL 60 S is diluted in water, it produces long molecular chains which deposit on the hole and core, increasing stability and integrity.
• Easy to destroy, by adding bleach or hydrogen peroxide (2l/M³ of mud).
• For fresh water only. For salted water, use POLYCOL 60 SM.

NATURE

Blend of polyacrylamides/sodium acrylates.

INSTRUCTIONS FOR USE

Determine the concentration:

• 0,5 Kg/M³ for hard rocks
• 1 Kg/M³ for instable layers
• 1,5 Kg/M³ for 100% core recovery in sandy, friable sandstones, powdery schists, gravels, alluvions

Pour POLYCOL 60 S slowly on a jet of water, or use a mixer. Do not use shale shakers to carry off cuttings from the mud.

When drilling, the polymer deposits on the sides of the hole, core and the cuttings to stabilize the walls, so it is necessary to add some product time to time when viscosity falls.

If the viscosity decreases too rapidly, maybe there is a problem of acidity. Add 0,2 Kg of soda ash by M³ of mud. POLYCOL 60 S is compatible with nearly all kinds of polymers for drilling muds. It’s incompatible with Bentonite and attapulgite muds.
