Process for natural gas production from hydrocarbon hydrates with simultaneous storage of carbon dioxide in geological formations

摘要

A method for recovering methane from methane hydrates comprising the steps of: feeding carbon dioxide to methane hydrate deposits, allowing the carbon dioxide to act on the methane hydrate to release methane and storing the carbon dioxide as the carbon dioxide hydrate, removing the released methane, characterized in that the supplied carbon dioxide is supercritical carbon dioxide ,
