The technology allows to increase wells productivity by treating the bottomhole formation zone with compounds containing powdery acids.

Purpose:

Producing oil- and gas-wells stimulation and increase of injection wells intake capacity. 

Content:

Powdery acids mixed with liquid carriers (dry oil, diesel fuel, gas condensate) and in combination with other inorganic acids are utilized for treatment of producing and injection wellbottom zones with deteriorated filtration characteristics. 

Specifics:

  • increase of acidized zone in productive formation;
  • low rust and corrosion effect on the oil-field equipment;
  • safe storage and transportation of acids to the operation site;
  • increased chemical activity of acid compound;
  • demulsification of watered oil;
  • decreased viscosity of oil rich in asphaltic-resinous substances. 

Range of application:

Producing and injection wells in terrigenous and carbonate productive reservoirs (including low-permeable ones).

Efficiency:

Application of the technology in the Ukrainian, Syrian and Chinese oilfields has proved to be 100% success. 

The system of technology application is environmentally friendly and harmless.

The technology has been successfully applied in the Turkmen fields (see chart 3 in Result).

.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.
