In the Pricetown I test, a 4-month burn affected some 735 tons of a 6ft-thick, high-sulfur, high-ash section of the 900-ft deep Pittsburgh coal seam. A methane-rich gas with an average heating value greater than 200 Btu/CF was produced at low-flow rates during initial operations to enhance the coal seam's permeability by reverse combustion. The high-flow-rate gasification phase produced a gas with an average heating value of 127 Btu/CF, resulting in an average energy production of 510.9 million Btu/day. Major problems identified during the test involved gas-condensate plugging during the reverse-combustion linkage stage, various difficulties that slowed the progress of linkage-path enhancement, and the need to design a casing for wells producing the hot pressurized gases.
