Abstract text

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 system.
