This book was released on 2010-11-15 with total page 238 pages. Available in PDF, EPUB and Kindle. Book excerpt: In some coalbeds, naturally occurring water pressure holds methane-the main component of natural gas-fixed to coal surfaces and within the coal. In a coalbed methane (CBM) well, pumping water from the coalbeds lowers this pressure, facilitating the release of methane from the coal for extraction and use as an energy source. Water pumped from coalbeds during this process-CBM 'produced water'-is managed through some combination of treatment, disposal, storage, or use, subject to compliance with federal and state regulations. CBM produced water management can be challenging for regulatory agencies, CBM well operators, water treatment companies, policy makers, landowners, and the public because of differences in the quality and quantity of produced water; available infrastructure; costs to treat, store, and transport produced water; and states' legal consideration of water and produced water. Some states consider produced water as waste, whereas others consider it a beneficial byproduct of methane production. Thus, although current technologies allow CBM produced water to be treated to any desired water quality, the majority of CBM produced water is presently being disposed of at least cost rather than put to beneficial use. This book specifically examines the Powder River, San Juan, Raton, Piceance, and Uinta CBM basins in the states of Montana, Wyoming, Colorado, New Mexico, and Utah. The conclusions and recommendations identify gaps in data and information, potential beneficial uses of CBM produced water and associated costs, and challenges in the existing regulatory framework.

This book was released on 2009 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Water quality is a major concern with regard to development of coalbed methane (CBM) in the Powder River Basin, Wyoming. Large quantities of water are being produced and discharged as a by-product in the process of releasing natural gas from coal. Current practices of discharging large volumes of water into drainage channels or using it to irrigate cropland areas has the potential to elevate salinity and sodicity in soils. Elevated salinity affects the ability of plants to uptake water to facilitate biochemical processes such as photosynthesis and plant growth. Elevated sodicity in irrigation water adversely affects soil structure necessary for water infiltration, nutrient supply, and aeration. Salinity and sodicity concentrations are important in that a sodic soil can maintain its structure if the salinity level is maintained above the threshold electrolyte concentration. In this study, cropland soil and CBM water were treated with gypsum and sulfur. Changes in soil chemistry among different treatments were monitored using a split plot experiment. The CBM water used for irrigation had an EC of 1380 [mu]S cm−1 and SAR of 24.3 mmol12 L−12. Baseline and post treatment soil samples were collected to a depth of 60 cm within each study plot, analyzed, and characterized for chemical parameters. Comparisons between Spring 2004 and Fall 2004 soil chemistry data after one irrigation season (using the equivalent of 1 month of irrigation water or ≈12 inches) indicated that irrigating with Piney Creek water or a 50:50 blend of Piney Creek water and CBM water did not cause SAR values to increase. A combination of using a gypsum amendment to the soil along with a gypsum injection and sulfur burner treatment to the irrigation water resulted in the lowest SAR value in the first soil horizon among treatments irrigated solely with CBM produced water. The SAR value resulting from this combination treatment was 53% lower than using CBM water with no amendments to soil or water. Soil amendments to cores in the laboratory did not increase soil hydraulic conductivity when CBM water was applied.

This book was released on 2009 with total page 176 pages. Available in PDF, EPUB and Kindle. Book excerpt: Coalbeds are a major source of methane gas, and coalbed methane accounts for about 10% of natural gas production in the U.S. Due to the recent rise in energy demand, there is a large incentive to develop new, cheap, and renewable natural gas supplies. The current estimate of unrecoverable coal in the U.S. is 234 billion short tons; if only 1% of this coal was converted to methane, current U.S. natural gas reserves would increase by 67%. Carbon isotope (13C) analysis has shown that coalbed methane gas in the Powder River Basin (Wyoming) is of biogenic origin. A field water sample from a coalbed methane well in the PRB tested positive for a methanogenic consortium, and is capable of producing methane from Wyodak sub-bituminous B coal. This consortium was enriched and maintained in a defined medium supplemented with 50 mg/L yeast extract and 16 g/L sub-bituminous Wyodak coal as the primary carbon sources. Results from this study showed that several factors affected methane production from coal: (1) stagnant cultures inoculated with 0.25 g coal, yeast extract, and cysteine yielded 22% greater final methane production compared to cultures without coal: there was nor difference in methane production between coal and no coal cultures when both cultures were agitated at 50 rpm and 100 rpm; agitation may have prevented the formation of microbial biofilms on new coal, leading to a decrease in methane production; (2) addition of sand as an inert surface did not improve methane production; however, the addition of clay enhanced methane production because clay provided carbon substrates for methanogenesis; (3) methane production was proportional to the concentration of cysteine in the culture medium, indicating that cysteine was used as a carbon source for methanogenesis; (4) the optimal concentration (for methane production) of sulfide in the culture medium was 0.42 mM; (5) maintenance cultures enriched with coal as the sole carbon source indicated that coal can be bioconverted to methane at levels as high as 14.2 umol/g coal/day (approximately 12 SCF/ton coal/day); (6) for cultures exhibiting low methanogenesis rates, methane production was not a function of coal particle size; (7) viable methanogens were also successfully enriched from water samples taken from the Niobrara aquifer in Spink County and Dolton aquifers in McCook County, South Dakota.
