Hasenmueller, W. A., and Rupp, R. F., 2017, Map showing thickness of the Clegg Creek Member of the New Albany Shale (Mississippian and Devonian) in Bartholomew County, Indiana: Indiana Geological and Water Survey Miscellaneous Map 107, scale 1:48,000.
Indiana Geological & Water Survey - Miscellaneous Map 107
Abstract:
"The computer-derived contours and color ramp on this map show the thickness of the Clegg Creek Member of the
New Albany Shale (Mississippian and Devonian) in Bartholomew County. The shaded relief on the map shows the
modern topography. The New Albany is an organic-rich shale that has been studied and explored extensively because it
is a potential source of hydrocarbon fuels. The Clegg Creek Member, near the top of the New Albany, has potential for
development as a source of hydrocarbon fuels. Hydrocarbons are not easily extracted from the New Albany, however,
because, like other oil shales, the New Albany is composed of fine-grained rock that does not allow the hydrocarbons
to flow freely to a conventional well. Various methods for extracting hydrocarbons from organic-rich shales have been
considered, and thickness of the potential resource is often a limiting factor in determining the technical feasibility of
an extraction technique. This map is intended to aid planners and explorationists in assessing the economic potential
of the Clegg Creek Member of the New Albany Shale in Bartholomew County."
