METHOD OF MULTILAYERED GAS FIELDS PRODUCTION Russian patent published in 2009 - IPC E21B43/14 

FIELD: oil-and-gas production.

SUBSTANCE: invention related to oil-and-gas production, can be used for multilayered gas fields development and production. Essence of the invention: method includes construction of production wells separate nets for each production object and pipelines. At that well, producing different production objects, connected to single pipeline. Field development start form lower gas reservoir production, which has bigger primary reservoir pressure, and add upper located reservoirs, when current well-head pressure, draining lower reservoirs, decreases till primary well-head pressure, draining upper reservoirs.

EFFECT: invention provides cost cutting and gas field construction time consumption decrease because of creating single pipeline for product withdrawal.
