Coalbed Methane Produced Water In The Western Us

Impurities within the source water are retained on the pressurized side of the membrane, and (nearly) pure water passes through the membrane to the other side. RO can remove salts, particulate matter, microorganisms, and organic and inorganic chemicals, depending on the membrane characteristics. Some pesticides and low-molecular-weight organics can pass through RO membranes (NRC, 2008). The RO process can remove 95 to 99 percent of any sodium, magnesium, calcium, barium, silica, sulfates,...

CBM produced water in the Raton-New Mexico, San Juan, Piceance, and Uinta Basins is almost exclusively reinjected into deep, geologic formations, as a means of disposal (Table 4.1). This approach is used in these basins because of the characteristically high FIGURE Proportional representation of CBM produced water management strategies in the Wyoming and Montana portions of the Powder River Basin. The total amount of water produced in the Wyoming Powder River Basin from CBM extraction in 2008...

Tribal Management of Coalbed Methane Development and Produced Water Coalbed methane CBM development on tribal lands is governed by the Omnibus Indian Mineral Leasing Act of 1938 and the Indian Mineral Development Act of 1982 see Chapter 3 . In a manner similar to that used elsewhere in the report, tribal approaches to CBM production and produced water management were examined in areas where tribal CBM production activity is greatest and or concerns over CBM produced water are most marked in the...
