SYSTEM FOR ASSOCIATED PETROLEUM GAS UTILISATION Russian patent published in 2014 - IPC E21B43/16 

FIELD: oil and gas industry.

SUBSTANCE: invention relates to oil and gas industry and can be used for injection of associated petroleum gas into the formation. The system consists of a producing well, a separator, a pump with electric motor, a water supply pipeline, a gas pipeline, a mixer and an injection well and a packer with a built-in pipe. The pump, the electric motor and the mixer are located inside the injection well. The pump is installed under the electric motor which is equipped with a housing connected to the water supply pipeline. Below the mixer, over or under the packer, there is an auxiliary booster pump. The booster pump can be equipped with its own electric motor. A centrifugal pump, a displacement pump, a diagonal-flow or axial-flow pump can be used as the booster and/or main pump.

EFFECT: mixing water with associated petroleum gas inside the injection well thus preventing developed structure at the surface and ensuring environmental safety due to exclusion of potential gas emissions into the atmosphere.
