FIELD: oil and gas production.
SUBSTANCE: gas hydrate field is reamed. A heat flow is generated. Methanol is synthesised by hydrocarbon gas (methane) oxidation outside of a gas hydrate decay zone by direct homogeneous hydrocarbon gas oxidation described by presented formula. Discharged hydrocarbon gas and formation water are separated. Methanol is supplied in a gas hydrate zone, and light-end reaction products are burned with heat and/or electric energy generated to produce a high-pressure heat flow supplied to the gas hydrate zone.
EFFECT: more efficient gas production from gas hydrate fields by increasing the debit, lower power consumption and improved ecological compatibility.
