Polyamine Biopolymer
Drilling fluids agent Consatone ®

Clay inhibitor, thermal stabilizer, microcolmatant

Polyamine biopolymer (clay inhibitor) is a multifunctional agent which improves inhibiting properties of water based drilling fluids; microcolmatant which controls filtration and improves rheological properties.

It is applied for fresh polymer-clay and mineralized biopolymer drilling fluids. It works in high temperature mode and ensures thermal stability of the solution during drilling. The mechanism of clay inhibition and suppression of clay minerals hydration is based on the processes of neutralization of negatively charged surfaces of clay particles with amine groups, potassium cations and functional groups of polysaccharides and polypeptides being a constituent of the Polyamine inhibitor.

Improves rheological properties, thinning of drilling fluids with a high content of the colloidal phase, preventing packing during drilling. Recommended for use in weighted drilling muds with high barite content.

Fields of application and purpose

Biodegradable and environmentally friendly product.

It is highly effective amine-based inhibitor for drilling unstable shale.

Increases the stability of the borehole walls.

Improves the rheological properties of the drilling fluid.

Does not reduce the permeability of productive reservoir, thereby excluding barriers to further inflow stimulation.
Reduces the filtration rate in drilling fluids at high temperatures.

Prevents the accumulation of colloidal clay phase in the drilling fluid.

Increases the thermal stability of the drilling fluid.

Effective at temperatures up to 180 °C.

Rates and recommendations

The recommended dosage is 2-15 kg/m3 in dry form, directly to the drilling mud, preliminary hydration of Polyamine biopolymer (inhibitor clay) is acceptable.
