Talk:Coalbed methane

message: Even if bacteria can continue to break down coal and produce methane, it's not renewable when the coal runs out. That might not happen for a thousand or a million years, but it's not infinitely sustainable.  Considering it "renewable" is still a minor and controversial opinion.  It's not unreasonable to assume that technology will some day develop which might enhance the in-situ production of methane from coal beds and thus make it run out that much faster.

thread_title:  Renewable Resource? 

message: 1) Open cavity completetion has played an very important role in CBM production and is nearly "unique" to CBM.  Missing from the article.
2) Strange and unspecific statement that "coal from alabama can have different Langmuir para compared to xx, despite otherwise similar coal properties." PETRSCIENT (talk) 04:05, 3 September 2009 (UTC)

message: Hi, I'd like to add some text about a 2010 United States National Research Council report on coalbed methane produced water:
:The water that must be pumped out to release methane from some coal beds is called "produced" water, and must be managed through some combination of disposal, use, or storage, and often requires treatment to remove salts and other compounds. Currently, the majority of the water is disposed of at least cost, rather than being put to beneficial use, for example, for irrigation and as drinking water for livestock. These potential beneficial uses have gained attention particularly in the western states where water is a much needed commodity. A 2011 National Research Council report investigated the critical environmental, economic, and regulatory issues associated with coal bed methane produced water. http://dels.nas.edu/Report/Management-Effects-Coalbed-Methane/12915The report noted that the extraction of water from coal beds and its eventual disposal or use can have either positive or negative impacts on soil, ecosystems, and the quality and quantity of surface water and groundwater. At present, no widespread negative effects have been documented. However, because coal bed methane production is a relatively young industry, these environmental impacts are not yet completely documented or understood http://dels.nas.edu/Materials/Report-In-Brief/4340-Coalbed-Methane. Produced water varies greatly in both quality and quantity depending on the geology of the coal basin from which it is extracted, but after any required treatment, the water could be put to beneficial uses. However, produced water is thought to accumulate over millions of years, making it essentially a nonrenewable resource, and therefore managing produced water carries with it the responsibility to take all environmental considerations into account, rather than simply choosing the management option that comes at the least cost. Furthermore, the consequences of removing these stocks of water on local groundwater systems have not yet been thoroughly investigated. Continued research to resolve gaps in information on the chemistry of coal bed methane produced water, its effects on the environment, and the regulatory framework to best govern it, would permit the development of more effective and sound coal bed methane produced water management practices.http://www.nap.edu/catalog.php?record_id=12915
I'd appreciate any feedback. Thanks, Earlgrey101 (talk) 22:54, 23 March 2012 (UTC)
thread_title: Propose adding reference to NRC report on coalbed methane produced water

message: In this documentary it was claimed that you can't tell coal gas from shale gas, based on the carbon-14.  According to the summary of this article, that is irrelevant; the gas from coal is nearly all methane, and the gas from shale is not.  I believe the Gasland documentarian was over their head and needed to consult with independent researchers.  It would have prevented this goof.  — Preceding unsigned comment added by 107.196.121.15 (talk) 17:28, 26 May 2013 (UTC)
