Abstract
A method and apparatus for producing gas from a hydrate formation includes the use of at least one wellbore which penetrates the hydrate formation and further extends into an aquifer 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 may be included to control the flow of water produced from the aquifer and gas produced from the hydrate formation.
Claims23
A method for recovering gas from a subterranean formation having a gas hydrate deposit located therein and wherein said formation further includes a liquid source, comprising the steps of:
- (a) providing a wellbore penetrating said gas hydrate deposit and extending into said liquid source;
- and
- (b) producing liquid from said liquid source into said gas hydrate deposit.
A method for recovering gas from a subterranean formation having a gas hydrate deposit located therein and further including a liquid source, comprising the steps of:
- (a) providing a first wellbore penetrating said gas hydrate deposit;
- (b) providing a second wellbore penetrating said liquid source and said hydrate deposit;
- (c) contacting said hydrate deposit with liquid from said liquid source to produce a gas;
- and
- (d) recovering said gas.
