• Start of work: 2013 to date (low-rate oil wells)

• Results: Over 160 oil and gas wells have been processed. A set of works was also carried out to level the injectivity profile through injection wells.

Water cut reduction from 94% to 45% on average. Increased individual well oil flow from 60% to 100% on average.

Ukraine

• Start of work: 2019 to date (low-rate oil wells)

• Results: Over 500 oil and gas wells have been processed. Efficiency: 88%. Reduction in water cut from 90% to 50% on average. More than 100,000 tonnes (750,000 barrel) of new oil were obtained.
