Assessment of Coal Bed Methane, Crawford County
David Morse is assisting Pioneer Oil Company of Lawrenceville, Illinois, to assess the amount of coal bed methane (CBM) in the Seelyville Coal in Crawford County, Illinois. Core was drilled by Pioneer in an area where they have an active CBM field. The Illinois State Geological Survey is desorbing the coal to determine its gas content and also, from the gas chemistry and isotopic analyses, will determine the origin (biogenic or thermogenic) of the gas. A company in Denver received part of the core and collected water from existing wells to study the microbes in the coal and find ways to stimulate even more CBM from formation. The coal desorption is on track to have the highest gas content measured to date in Illinois.
