Conclusions • Gas Contents of the Horseshoe Canyon/Belly River Coals Do Not Follow Anticipated Trends • Gas Content Variations are Due to: – Service Company and Technique – Ash Content, – Reservoir Pressure • Seam, Location, and Depth
– Storage Capacity • Coal Rank and Temperature → Adsorption Isotherm Coal Gas Technology Ltd.
