Annotation:
The main production facilities of the Dragon field are currently being at the stage of declining production due to a decrease the active reserves, water-flooding and wells abandonment. The reservoir pressure decrease and the appearance of water in the well production caused the cessation of flowing, which was accompanied by an increase of downtime, a decrease of the sweeping efficiency and the rate of oil recovery. The application of the biotechnology based on enzyme complexes will ensure increase of oil flow rates of producing wells, reduce the water-flooding growth rate of products and obtain a positive technical-economic effect.
