Unconventionals in Michigan: The A-1 Carbonate and Collingwood and Utica Shales

Live Date: September 29, 2011 Time: 10:00 am CT Cost: $100


The Michigan Basin is home to several emerging unconventional plays. The Ordovician Collingwood and Utica shales both show promise in the region. A likely liquids-rich resource play targeting the Silurian age A-1 Carbonate is also fast developing in the region. Some have compared the A-1 Carbonate to the middle member of the Bakken shale at prolific Parshall Field in North Dakota.

Companies including Devon Energy are devoting capital to these resource plays. This webinar offers an overview of the A-1 Carbonate and Collingwood and Utica shales, what is known about their thickness, areal extent and reservoir characteristics, and an update on recent activity, including leasing programs and permitted and drilled wells.

What you will learn:

  • Overview of geology and potential of Michigan’s emerging unconventional plays
  • General activity and objectives in the Michigan Basin
  • Status of Michigan’s regulatory environment
  • Potential for H2S production from unconventional reservoirs


Dr. William B. Harrison, III, Professor Emeritus and Director, Michigan Basin Core Research Laboratory, part of the Michigan Geological Repository for Research and Education, Department of Geosciences, Western Michigan University

Dr. Harrison is a research professor and director of the Michigan Basin Core Research Laboratory at Western Michigan University in Kalamazoo. He began his career as a professor at Western Michigan University in 1973, and he founded the laboratory in 1982 to preserve and research geological samples and data related to Michigan’s subsurface formations and natural resources. Harrison is also the director of the Michigan Center, Midwest Region, Petroleum Technology Transfer Council. He has published more than 30 technical papers on Michigan geology and authored or co-authored more than 70 technical presentations at conferences, professional meetings and workshops. Harrison obtained a B.A. and M.A. in Geology from the University of South and a Ph.D. from the University of Cincinnati.
