Organic substances in produced and formation water from coalbed methane (CBM) and gas shale plays from across the USA were examined in this study. Results from five CBM plays and two gas shale plays (including the Marcellus Shale) show a myriad of organic chemicals present in the produced and formation water. Organic compound...

The U.S. Geological Survey, in partnership with the U.S. Bureau of Land Management, the North Slope Borough, and the Arctic Slope Regional Corporation conducted a four-year study designed to identify, define, and delineate a shallow coalbed natural gas (CBNG) resource with the potential to provide locally produced, affordable power to the community of Wainwright, Alaska.

The gas released from coals under hydrous pyrolysis conditions represents a quantifiable mixture of ancient (270 Ma) methane (likely microbial) that was generated in situ and trapped within the rock during the rapid heating by the dike, and modern (laboratory) thermogenic methane that was generated from the indigenous organic matter due to thermal maturation induced by hydrous pyrolysis conditions. These findings provide...

Natural gas is an important component of the energy mix in the U.S, producing greater energy yield per unit weight and less pollution compared to coal and oil. Most of the world's natural gas resource is thermogenic, produced in the geologic environment over time by high temperature and pressure within deposits of oil, coal, and shale. About 20 percent of the natural gas resource, however, is produced by microorganisms (microbes). Microbes potentially could be used to generate economic quantities...

Coal formation dewatering at a site in the Powder River Basin was associated with enhanced potential for secondary biogenic methane determined by using a bioassay. We hypothesized that dewatering can stimulate microbial activity and increase the bioavailability of coal. We analyzed one dewatered and two water-saturated coals to examine possible ways in which dewatering influences coal bed natural gas biogenesis by looking at differences with respect to the native coal microbial community, coal-methane...

USGS Publication: Scientific Investigations Report 2011–5010
This report discusses the geologic framework and petroleum geology used to assess undiscovered petroleum resources in the Bohaiwan basin province for the 2000 World Energy Assessment Project of the U.S. Geological Survey. The Bohaiwan basin in northeastern China is the largest petroleum-producing region in China.

The U.S. Geological Survey (USGS) John Wesley Powell Center for Analysis and Synthesis is hosting an interdisciplinary working group of USGS scientists to conduct a temporal and spatial analysis of surface-water and groundwater quality in areas of unconventional oil and gas development. The analysis uses existing national and regional datasets to...
Methane and other gases, while frequently produced with petroleum, also occur in association with coal. Coalbed gas accounts for about eight percent of U.S. natural gas production. U.S. estimates (Rice, 1997) indicate more than 700 trillion cubic feet (TCF) of coalbed gas in place, with over 100 TCF economically recoverable--a five-year supply at present rates of consumption.
The USGS Energy Resources Program assesses potential U.S. coalbed gas resources including controls on the occurrence and recoverability, (including produced water) and geologic, geochemical, engineering, and technological factors.
The USGS Energy Resources Team examines environmental considerations with coalbed natural gas development (CBNG) nationwide. A major portion of this is on water co-produced with CBNG, which is provided in the Energy Program’s "Produced Waters" topic.
Several Energy Resources Program coalbed methane assessments for the United States are currently available.
The USGS Energy Resources Program is also focused on international cbm assessments and issues. Here are a few specific areas that may be of interest... [+]
