Claims (2)

1. A method for developing a gas condensed or oil and gas condensate deposit comprising maintaining a pressure in the hydrocarbon-containing layer by means of gas and / or water, characterized in that the pressure is provided by the introduction of a layer of gas and / or water from below. placed in an aqueous layer. Method according to claim 1, characterized in that the introduction of gas and / or water is effected by contacting the aqueous layer with flexible oscillations.
