Zusammenfassung:	FIELD: gas and oil production industry. SUBSTANCE: method can be used for development of deposits located near trunk pipelines. According to method, selected in each dome assigned for drilling are two sections. Drilled in first section are wells by incline-directed method with maximal deviation of 1750 m. Drilled clusters of wells in each dome are successively connected to each other by telescopic conduit. Diameter of conduit is discretely increased after each dome as it extends towards trunk pipeline. In process of operation, gas from dome, which is farthest from trunk pipeline is delivered to conduit without special treatment. Gas from next dome is delivered after separation, and gas from nearest dome is delivered after separation and absorption. Technological equipment for treatment of gas or condensate is standard and can be used for various fluids. Application of aforesaid method simplifies technological process, thus reducing cost of equipment. EFFECT: higher efficiency. 1 cl
