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.

Rates andrecommendations
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.
