A PROCESS AND A SYSTEM FOR CONTROLLED PRODUCTION AND COLLECTION OF METHANE GAS FROM AN UNCONSOLIDATE MARINE SYSTEM

摘要

The invention relates to a process and a system of producing methane gas from a marine system. Production of methane gas from an unconsolidated marine system with gas hydrate deposits by successive steps simultaneous or sequential usage of electric heating using dome-electrode system, pumping hot water, injecting CO2 from a drill head and reducing the pressure placed in a pre-drilled well head. The dome for collecting the produced gas in a confined manner without leakage into the atmosphere. The invention also pertains to a system to execute the invented process.
