Abstract
A gas hydrate formation is treated by horizontally fracturing the formation, placing electrically conductive proppant particles in the fracture, and passing an electric current through the proppant particles in the fracture to generate sufficient heat to release gas from the hydrate. The method has particular application in shallow gas-bearing formations underlying or within the permafrost.
