METHOD AND SYSTEM FOR EXTRACTING HARD-TO-REACH GAS FROM UNDERWATER MEDIA, CONVERSION THEREOF INTO CLATHRATES AND SAFE TRANSPORTATION FOR CONSUMPTION Russian patent published in 2020 - IPC C07C1/12 C10L3/10 E21B43/24 

FIELD: oil and gas industry.

SUBSTANCE: invention relates to versions of a method of extracting natural gas from hydrocarbon reservoirs for oil and gas in an underground medium. One of the versions of the method includes: (a) if necessary, drilling a well in the ocean bottom for extraction of hydrocarbons in form of natural gas or a mixture of oil and natural gas; (b) extracting hydrocarbons in form of natural gas or a mixture of oil and natural gas; (c) separating oil from natural gas in a separator; (d) if necessary, transportation, pumping or supply via oil pipeline to ocean surface; (e) purifying natural gas from debris; (f) transporting, pumping or supplying natural gas through pipeline to underwater apparatus for converting gas into clathrate hydrate; (g) converting natural gas to obtain solid hydrates therefrom; (h) collecting solid hydrates into a transport container suitable for transporting solid hydrates to the ocean surface.

EFFECT: method enables to obtain natural gas from underwater media efficiently and environmentally and safely transported for consumption.
