1. A system for extracting methane gas from a hydrate formation, said system comprising:
- a plurality of wellbores extending into the hydrate formation;
a column of modified material substantially filling wellbores and in direct contact with the hydrate formation;
a heat source operable to provide heat to said modified material, wherein the heat is transferred through said modified material to the hydrate formation so as to release methane gas from said formation; and
gas collector means operable to control the flow of methane gas out of said formation

Abstract
Methods and apparatus for producing methane gas from a hydrate formation. A column of modified material substantially filling a wellbore extending into the hydrate formation. The column of modified material is permeable to gases. A heat source extends into the column of modified material and is operable to provide heat to the hydrate formation so as to release methane gas from the hydrate formation. Methane gas flow through the column of modified material to a gas collector, which regulates the flow of gas to a production

9. A method for extracting hydrocarbon gases from a hydrate formation, the method comprising:
-
drilling a wellbore into the hydrate formation;
substantially filling the wellbore with a modified material that is permeable to gases, supplying an oxidizer to a heat source in said modified material operable to provide combustion to fuel at said heat source and to heat said modified material so as to heat the hydrate formation and release hydrocarbon gases from the formation; and
collecting at least a portion of the hydrocarbon gases that flow into the wellbore.
