To increase productivity of oil-wells equipped with sucker-rod pumping units (SRPU) when recovering watered oil. 


Injecting water solution of high molecular weight compound (HMC) into the annular space of the running well improves hydrodynamic operating conditions and reduces hydraulic resistance in SRPU. 

Range of application:

SRPU-equipped wells with watered output. 


  • fluid leakages in pump element and threaded connections of the tubing string diminish significantly;
  • improvement of hydrodynamic characteristics of the lift due to reduced hydraulic resistance factor;
  • increasing of the well overhaul period. 


Technology’s application in the Ukrainian and Chinese oil fields has proved its high efficiency (over 80%). The effect duration is 20-60 days. 



.Operation results on oil fields in Azerbaijan, Bulgaria, China, Cuba, Poland, Russia, Syria, Turkmenistan and Ukraine have shown that after the Company’s technologies application the oil production increases from 2 to 5 times and even more. After well workover the duration of well’s operation at increased level of yield is from 6 months to 2 years.
