METHOD FOR OPERATION OF UNDERWATER GAS AND GAS CONDENSATE FIELD AND UNDERWATER EJECTOR FOR ITS IMPLEMENTATION Russian patent published in 2023 - IPC E21B43/36 

FIELD: gas industry.

SUBSTANCE: inventions group relates to a method for operating an underwater gas and gas condensate field and an underwater ejector module for its implementation. The method for operating an underwater gas and gas condensate field consists in connecting one of the gas pipeline pipes to a high pressure source on the shore. Through one of the pipes or pipes, high-pressure gas from the shore is directed under water, where it enters the ejector or as an ejecting medium and the gas fluid is compressed in the ejector. The ejected medium entering the subsea ejector is gas fluid from the field. Further, the total flow of the ejecting and ejected media enters another pipe or pipes and is directed to the shore for compression in the BCS. Underwater compression of the gas fluid in the ejector or ejectors is carried out due to the energy of the part of the produced gas recirculated from the shore under the water. The ejectors are located as part of the underwater ejector module.

EFFECT: increase in the total production rate of a field with two or more pipe gas pipelines in a period of declining production.
