RESOURCE ASSESSMENT & PRODUCTION TESTING FOR COAL BED METHANE IN THE ILLINOIS BASIN

Description: The geological surveys of Illinois, Indiana and Kentucky have completed the initial geologic assessment of their respective parts of the Illinois Basin. Cumulative thickness maps have been generated and target areas for drilling have been selected. The first well in the Illinois area of the Illinois Basin coal bed methane project was drilled in White County, Illinois in October 2003. This well was cored in the major coal interval from the Danville to the Davis Coals and provided a broad spectrum of samples for further analyses. Sixteen coal samples and three black shale samples were taken from these cores for canister desorption tests and were the subject of analyses that were completed over the following months, including desorbed gas volume, gas chemical and isotope composition, coal proximate, calorific content and sulfur analyses. Drilling programs in Indiana and Kentucky are expected to begin shortly.

Resource Assessment & Production Testing for Coal Bed Methane in the Illinois Basin

Description: In order to assess the economic coal bed methane potential of the Illinois Basin, the geological surveys of Illinois, Indiana and Kentucky performed a geological assessment of their respective parts of the Illinois Basin. A considerable effort went into generating cumulative coal thickness and bed structure maps to identify target areas for exploratory drilling. Following this, the first project well was drilled in White County, Illinois in October 2003. Eight additional wells were subsequently drilled in Indiana (3) and Kentucky (5) during 2004 and 2005. In addition, a five spot pilot completion program was started with three wells being completed. Gas contents were found to be variable, but generally higher than indicated by historical data. Gas contents of more than 300 scf/ton were recovered from one of the bore holes in Kentucky. Collectively, our findings indicate that the Illinois Basin represents a potentially large source of economic coal bed methane. Additional exploration will be required to refine gas contents and the economics of potential production.

Significance of Isotopically Labile Organic Hydrogen in Thermal Maturation of Organic Matter

Description: Isotopically labile organic hydrogen in fossil fuels occupies chemical positions that participate in isotopic exchange and in chemical reactions during thermal maturation from kerogen to bitumen, oil and gas. Carbon-bound organic hydrogen is isotopically far less exchangeable than hydrogen bound to nitrogen, oxygen, or sulfur. We explore why organic hydrogen isotope ratios express a relationship with organic nitrogen isotope ratios in kerogen at low to moderate maturity. We develop and apply new techniques to utilize organic D/H ratios in organic matter fractions and on a molecular level as tools for exploration for fossil fuels and for paleoenvironmental research. The scope of our samples includes naturally and artificially matured substrates, such as coal, shale, oil and gas.
