A method and apparatus for producing gas from a hydrate formation includes the use of at least one wellbore (10) which penetrates the hydrate formation (14) and furtherr extends into an aquifer (12) below the hydrate formation. The aquifer provides relatively warm water which may be produced up and into the hydrate formation thereby causing the release of gas from the hydrate. Suitable flow control and monitoring equipment (30) may be included to control the flow of water produced from the aquifer and gas produced from the hydrate formation.
L'invention porte sur un procédé et un appareil de production de gaz à partir d'une formation d'hydrates consistant: à utiliser au moins un forage (10) pénétrant la formation d'hydrates (14) et se prolongeant dans une formation aquifère (12) située sous la formation d'hydrates (14). La formation aquifère (12) fournit de l'eau relativement chaude en remontant dans la formation d'hydrates (14) y provoque la libération de gaz. On peut inclure des équipements appropriés (30) pour gérer les flux d'eau produite par la formation aquifère (12) et de gaz produit par la formation d'hydrates (14).
