Multifunctional polyamine biopolymer: clay and shale swelling inhibitor, fluid thinner with bactericidal effect
Polyamine biopolymer is a new generation drilling agent.
The multicomponent composition and production technology make this product multifunctional. It works without loss of efficiency even in high temperature mode. Suitable for drilling fluids on water and oil base.
Shows properties as a highly effective organic inhibitor of hydration and swelling of clay and shale. 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 and potassium cations of the polyamine biopolymer. Improves rheological properties, bearing capacity, thinning, filtration and fluid loss control.
Bactericidal components prevent the biodegradation of organic components of the drilling fluid and help to suppress the activity of sulfate-reducing bacteria that emit toxic H2S gas and cause biocorrosion of equipment and pipelines.
The use of the polyamine biopolymer can significantly reduce or eliminate the use of such agents in drilling fluids as: thinners, bactericides, various types of inhibitors, OBM filtration reducers, gilsonites and asphaltites.

Rates and recommendations
Add 2-25 kg/m3 to all types of drilling fluids either in dry form (directly adding to the solution) or with preliminary hydration of biopolymer in water. The dosage is adjusted depending on the following: the required level of inhibition, type of shale, borehole diameter, rate of drilling, as well as the desired degree of filtration control and fluid loss.
It may be necessary to increase the dosage to 30-35 kg/m3 for special applications where high temperatures are expected or where ultra-low fluid loss is required.
