Water-repellent, corrosion inhibitor, biocide
Don-А 0834 is a water or alcohol composition of cationic nitrogen surfactant.
It can be used as a water-repellent for bottom-hole zone oil and water-injection wells in order to enhance their output. It can also be used in muffling liquids and drilling solvents to remove bound water out of a layer, also for water-repellency treatment of a steam surface. Moreover, also it’s possible to use as a water-repellent, combining with other physico-chemical methods of oil and gas extraction to intensify this process.
It can also be used to prevent carbon dioxide and hydrogen sulfide corrosions, as a biocide of sulfate-reducing bacteria. It is used to obtain hydrochloric acid, which is used for oil and gas wells treatment to improve oil recovery. It’s compatible with the most kinds of demulsifies. It is soluble in water.
Recommendation on concentrations:
– 0,5-1,5 % as a water-repellent;
– 30-150 g/м3 as a corrosion inhibitor;
– 15-30 g/м3 for bacteriostatic effect;
– 50-150 g/м3 for suppressing the growth of sulfate-reducing bacteria
