DON-А 0934
Water-repellent
The reagent is a mixture of cationic surfactants in an alcohol solvent
Application
The water repellent is intended for use as a part of drilling fluids, silencing fluids, acid solutions for the treatment of the bottom-hole zone of the formation in conditions of thermosalt aggression. It is used to remove bound water from the reservoir and hydrophobize the pore surface. It is characterized by lower values of interfacial tension at the boundary with oil compared to analogues, has a higher oil-bearing capacity and retains phase stability in a wide temperature range (5-95 ° C) regardless of the degree of water mineralization. It is mixed with water in unlimited quantities.
Recommended working concentration:- 15-100 g/m3.
