Comprehensive approach to hydrochemical analysis of produced water of Urengoy oil and condensate field

Complication of hydrocarbonproduction technology under conditions of declining well rate has broughtthe necessity of improvement the physicochemical methods of produced water analysis.Comprehensive approach to hydrochemical analysis of stratal water with application of instrumental and titrimetric methods was introduced to carry out of hydrochemical monitoring for drowning of Urengoy oil, gas, condensate field in Engineering and Technical Center of Gazprom dobycha Urengoy LLC. Improvement of produced water analysis is based on the adaptation of modern laboratory equipment anddevelopment of new physical and chemical procedures.Comprehensive approach allows to solve one of the key problems of hydrochemical monitoring of Urengoy oil, gas, condensate field - determination of hydrochemical correlatives depending on theproducing depth, which assist to realize organizational or engineering decisions on efficient use of operating wells fund.
Materials and methods
Sampling material of producedwater; anionic, cationic composition;titrimetric and instrumental methods.
Results
Adaptation of modern laboratory equipment, development and application ofnew physical and chemical procedures of produced water of Urengoy oil, gas, condensate field are intended to carry out comprehensive approach to hydro-chemical analysis of produced water.
Сonclusions
The basal data of comprehensive hydrochemical analysis provide an opportunity to find hydrocarbon correlatives and define produced water genesis.
