Abstract
Any desired number of alternate parallel rows of injection and production well bores are positioned to establish a block gasification pattern. Combustion links are established between adjacent injection and production well bores in a direction generally perpendicular to said rows. The block pattern is ignited simultaneously through all of the injection well bores such that the pattern is gasified along the multiple linking paths in both directions between each injection well bore and its adjacent production well bores. In this manner the entire area of deposit defined by the block pattern is gasified simultaneously and may be separated from other similar block patterns by a barrier, thereby eliminating the problem of direct contact with burned-out areas.
