DON-А 0834
Biocide
The reagent is a mixture of cationic surfactants in an alcohol solvent
The reagent is designed to suppress biocenosis in the bottom-hole zone of the injection well formation, sterilize water injected into the formation, and protect metal surfaces of oilfield equipment and pipelines from hydrogen sulfide, caused by the vital activity of SRB and carbon dioxide corrosion.
Application
The reagent is used at oil production and treatment facilities. The bactericide delivery point shall be provided in the technological scheme, taking into account the features of the oil treatment plant and the maintenance of reservoir pressure and technological regulations. Compatible with the vast majority of demulsifiers, soluble in water.
Recommended working concentrations: 50 — 500 g/m3 depending on the number of planktonic forms of SRB in the treated medium.
