The article substantiates the conditions for effective water and gas impact on productive formations of the Upper Jurassic and Achimov deposits of the Vyintoy oil field: for the UJ formation, alternate injection of “wet” gas and water (gas injection for 3 months – water injection for 3 months) with a maximum intake capacity of gas injection wells of 15 thousand m 3 per day with a total volume of gas agent injection of 20 % of the pore formation volume; for the Ach formation, continuous injection of “wet” gas with a maximum intake capacity of gas injection wells of 30 thousand m 3 per day.
