Coalbed Methane Produced Water Organic Matter Characterization: Contribution, Origin, and Potential Impact on Membrane Treatment Technologies
Coalbed methane (CBM) is an unconventional gas source with large worldwide reserves. CBM wells are screened along coal seams, where water is produced to release pressure and allow methane to desorb from the coal surface (Orem, 2007). This practice has environmental impacts from disposal of co-produced, highly saline water. Industry treats co-produced water as a waste product. Water is commonly re-injected back into deeper aquifers for disposal. Lack of aquifer storage capacity directly limits gas production unless a solution for water treatment can be found. Regions in the US where CBM occurs ...
