What is In-Situ Coal Gasification (ISCG)?
ISCG is gasification of coal deep underground in its original coal seam. The ISCG process uses injection and production wells drilled from the surface to access the coal seam and facilitate the process in-situ. The coal is not extracted to the surface as there is no coal mine or coal handling facilities with ISCG. Through a high pressure gasification process, the coal is efficiently converted in-place in its original seam into syngas. The syngas is flowed to the surface and is then processed in a conventional gas plant to produce fuel for electrical power generation or used to produce other products.
