Polyamine Inhibitor 369 is an up-to-date all-weather (can be stored at sub-zero air temperatures) polyamine inhibitor for clays and shale which effectively suppresses hydration and swelling of clay formations.
Polyamine inhibitor 369 prevents dispersion of mud cuttings; helps to decrease the risk of bit balling and BHA. Polyamine inhibitor 369 allows to stabilize the wellbore in shale formation intervals, reduce the operating time and dilution ratio of the solution. It prevents from screens sticking and improves the efficiency of mud cleaning equipment.

Upon agreement with the customer, can be supplied in alternative packaging: - Plastic barrels of 200 / 220 liters - Plastic IBC - Plastic cans of 10 liters, 20 liters, 30 liters
Fields of application and purpose
It is an active inhibitor of clay materials hydration.
Acts as a powerful organic shale inhibitor.
Does not affect the electrical conductivity of the solution.
It forms an impervious surface on the well wall, prevents the penetration of the filtrate into the rock structure.
It is thermally stable (up to 200 °С).
Effective over a wide pH range.
Does not affect the rheological and filtration properties of the solution.
The reagent can be added either directly into the containers when preparing the solution or through a mixing funnel. There is no need to use additional equipment or special measures to process the solution.
It is possible to treat both like the active drilling fluid or to prepare a concentrated agent solution in a separate container for subsequent processing of an active solution. The standard concentration of the product depending on the drilling conditions is 10–20 kg/ m3.
