Abstract
A heating system for heating a natural gas hydrate reservoir. The heating system includes a fully enclosed wellbore extending through a portion of the natural gas hydrate reservoir. A heating fluid is passed through the wellbore to heat the portion of the natural gas hydrate reservoir. Additionally, a production system includes a perforated wellbore that is used to extract the natural gas hydrate water after heating.
Claims20
A method of heating natural gas hydrate, the method comprising:
- forming a fully enclosed well through a portion of a natural gas hydrate reservoir, the reservoir containing natural gas hydrate;
- and
- passing a heating fluid through the well to heat the natural gas hydrate in the portion of the natural gas hydrate reservoir.
A method of producing natural gas hydrate from a natural gas hydrate reservoir, the method comprising:
- heating a portion of the natural gas hydrate reservoir by passing a heating fluid through a non-perforated wellbore;
- perforating the wellbore after heating the portion of the natural gas hydrate reservoir;
- and
- extracting natural gas hydrate water from the natural gas hydrate reservoir through the wellbore.
A fully enclosed wellbore extending through a portion of a natural gas hydrate reservoir.
A heating system comprising:
- a fully enclosed wellbore extending through a portion of a natural gas hydrate reservoir, the wellbore including a first end and a second end;
- and
- a fluid pump configured to pump a heating fluid through the wellbore to heat the portion of the natural gas hydrate reservoir.
