Eastern in situ coal gasification field trial
A 900-ft (275-m) deep, 6-ft (2-m) thick, swelling, eastern bituminous coal has been gasified successfully in situ. The relatively small-scale field test, Pricetown I, affected the equivalent of 735 tons (665 t) of a high-sulfur, high-ash section of the Pittsburgh coal seam near Pricetown, Wetzel County, West Virginia, during the 4-month burn. A methane-rich gas with an average heating value greater than 200 Btu/ft/sup 3/ (7450 KJ/m/sup 3/) was produced at low-flow rates during operations to enhance the coal seam permeability by reverse combustion. During the high-flow rate gasification phase, a gas with an average heating value of 127 Btu/ft/sup 3/ (4260 KJ/m/sup 3/) was produced, resulting in an average energy production of 510.9 MMBtu/day (539.1 GJ/d). Initial test results and plans for continued development of this alternative energy source are discussed. 6 refs.
