Rocks To Roads To Ruin: A Brief History Of Western Kentucky’S Rock-Asphalt Industry, 1888–1957, J. Richard Bowersox

Heavy-Oil And Bitumen Resources Of The Western Kentucky Tar Sands, J. Richard Bowersox

Report of Investigations--KGS

Heavy-oil and bitumen resources in western Kentucky are present in the Upper Mississippian Big Clifty and Hardinsburg Sandstones and Lower Pennsylvanian Kyrock and Bee Spring Sandstone Members of the Caseyville Formation in a belt extending from Logan County on the south to Breckinridge and Hardin Counties on the north.

Net oil-saturated intervals in the tar sands range from 2.5 to 4.7 m thick, largely in downthrown fault blocks in and bounding the Rough Creek Graben. Records from 1,500 wells, analysis of reservoir properties from 3,769 plugs from 135 coreholes, and bulk volume of hydrocarbon calculated in 139 surface samples were …
