Petroleum Systems of the Michigan Basin— A look at Remaining and Undiscovered Oil and Gas Resources

At the Crowne Plaza, Grand Rapids, MI on September 23, 2004 from 8:30am to 4pm

• Come learn about the work of geoscientists from the USGS who have been studying samples and data from the Michigan Basin to estimate undiscovered oil and gas resources
• Hear a State geologist describe how historical exploration can forecast potential opportunities that may remain
• See how structure and isopach maps for both potential petroleum source rocks and known producing horizons can be used to visualize their prospectivity
• See the source rocks in cores and cuttings
• Learn from geoscientists at the University of Houston about how their work on imaging seismic features in Trenton-Black River rocks in other areas might have implications for the Michigan Basin
• Hear the thoughts of a panel of Michigan independents who worked with the USGS

The information and concepts presented at this workshop may well shape Michigan’s oil and gas production in the coming decade.

Come share the excitement!

Agenda and Program: 8:30-9:00--Registration, welcome and refreshments 9:00-9:40--Dr. Christopher S. Swezey, Research Geologist, U. S. Geological Survey, will introduce the work of the U.

S. Geological Survey (USGS) on an oil and gas assessment of the Michigan Basin, and how the USGS uses the concept of "petroleum systems" to estimate undiscovered oil and gas resources. He will review the petroleum systems of the Michigan Basin, and focus on several reservoir intervals with remaining potential for undiscovered hydrocarbons. Chris obtained a Ph.D. in geology from the University of Texas at Austin in 1997, and he has worked for British Petroleum, BP Amoco, Phillips Petroleum, and the Texas Bureau of Economic Geology. About 4 years ago, he joined the USGS Eastern Energy Resources Team, where he has worked on oil and gas assessments of the Appalachian Basin and the Michigan Basin.

9:40-10:10--Jim Duszynski, Senior Geologist and Permit Coordinator with the Geological and Land Management Division of the Michigan Department of Environmental Quality, will review the history of oil and gas production in Michigan. He will show that production cycles track technology and interpretive success of the major basin plays and discuss how historical exploration can forecast potential opportunities that may remain. A Michigan State University graduate, Jim has personal oil field experience from the Albion-Scipio discovery through 3-D seismic imaging, as an observer and explorer. Jim has served two decades with State government and 11 years in the industry, exploring from West Virginia to Colorado and Oklahoma to Alpena. His current interests are work on a Subsurface Hazards Database of geological drilling problems with suggested successful countermeasures.

10:10-10:25--Coffee break

10:25-10:55--Dr. A. S. (Buddy) Wylie, Research Scientist/Engineer with Michigan Technological University, will share the structure and isopach maps he created of potential petroleum source rocks and producing horizons in Michigan. Using these maps, we can visualize the prospectivity of subsurface formations. Based on data from the Michigan Department of Environmental Quality oil and gas information system, he mapped these potential source rocks: Antrim, Amherstberg, Salina, Niagara, Collingwood, and Foster Formations. Producing horizons mapped include: Michigan Stray, Berea, Antrim, Traverse Group, Dundee, Detroit River, Richfield, Sylvania, Salina A-1, Niagara, Burnt Bluff, Trenton/Black River, St. Peter, and Prairie du Chien/Glenwood. Where available, historical annual production plots were posted on the maps, showing both annual production and cumulative production vs. time. These formations continue to produce important quantities of oil and gas in Michigan and many have significant remaining exploration and exploitation/EOR potential. Buddy has worked for 20 years in industry in petroleum exploration and reservoir characterization.

10:55-11:25--Dr. Joseph R. Hatch, Research Geologist, U. S. Geological Survey, will summarize work characterizing the hydrocarbon source-rock potential and geochemistry of natural gases and oils produced from the five significant Paleozoic petroleum systems in the Michigan Basin. Joe obtained a Ph.D. in geology from the University of Illinois in 1972 and has worked at the U. S. Geological Survey in Denver since 1974. Previous relevant experience includes studies of hydrocarbon source-rock potential, oil geochemistry, and oil-source rock correlations in the Paleozoic sections of the Anadarko, Forest City, Salina, Illinois and Appalachian basins, assessments of coal-gas resources in the Black Warrior, San Juan, Illinois and Arkoma basins and Cherokee platform, and assessments of shale-gas resources in the Illinois and Appalachian basins.

11:25-12:00--Dr. William B. Harrison, III, Professor Emeritus and Director of the Michigan Basin Core Research Laboratory in the Department of Geosciences, Western Michigan University, will present a core workshop from the specific source rocks identified by Joe Hatch. He will also review the resources available at the Core Laboratory for exploration and prospect identification including: Geological publications, geologic and subsurface maps, drillers’ reports, well scout data, oil and gas well production data, well test data, various types of wireline logs, drill cuttings samples, drill core samples and related well and geological information. Bill founded the Core Lab 21 years ago, and has authored dozens of papers on Michigan geology.

12:00-1:00--Lunch

1:00-1:40--Dr. John E. Repetski, Research Geologist, U.S. Geological Survey, will present and discuss thermal maturation isograd maps, based on conodont color alteration index (CAI), for two stratigraphic intervals in the Michigan basin: (1) the Lower to lower Middle Ordovician [including the Prairie du Chien Group, and "Foster" and "Bruggers" formations], and (2) the Upper Ordovician [including the Black River and Trenton Groups]. These maps, and the conodonts analyzed to construct them, can be used to help determine the basin's burial history and thermal evolution, as well as to solve stratigraphic problems. Since obtaining his Ph.D. in geology at the University of Missouri-Columbia, John has spent almost 30 years with the USGS. He has worked with conodonts from all continents, concentrating primarily on North American Cambrian and Ordovician. He has applied conodont work to diverse projects, ranging from mapping, groundwater, earthquake hazards, and mineral and energy resource assessments.

1:40-2:10--Dr. Daniel O. Hayba, Research Geologist, U.S. Geological Survey, will present results from a basin evolution modeling study of the Michigan Basin. This research involved both 1-D and 2-D simulations of stratigraphic evolution, heat transport, and fluid migration. The parameters used to construct the model are derived from an analysis of digital lithologic and electric logs. A basin-wide synthesis of thermal maturation data was used to constrain the model and to predict the timing of maturation. Dan has been with the USGS for more than 20 years and has been involved in various aspects of numerical modeling for nearly 15 years.

2:10-2:25—Coffee break

2:25-3:00--Dr. E. Charlotte Sullivan, Research Assistant Professor at the Allied Geophysical Laboratories, University of Houston, Dr. Kurt Marfurt, Director of the Laboratory, and C.H. “Chuck” Blumentritt, Researcher at the Laboratory, will address their work on imaging features in Trenton-Black river rocks in the Appalachian Basin with implications for similar work in the Michigan Basin. They will discuss recent advances in geometric seismic attributes at the AGL,

and application of this technology to the imaging of fracture, joints and small-scale faults, and to the goal of separating seismic signatures related to paleokarst, hydrothermal processes and tectonic collapse features. They will illustrate their work through examples from Texas, the Appalachian and Michigan Basins, and Canada. Charlotte has 30 years’ industry experience with a focus on carbonate reservoirs in the Philippines, Qatar, Trinidad, Mexico, West Texas, New Mexico, and the Eastern U.S. Currently she spends considerable energy on the calibration of seismic attributes. Kurt has worked both in academia and industry and has spent the last 23 years doing or leading research efforts in modeling, migration, signal analysis, basin analysis, seismic attribute analysis, reflection tomography, seismic inversion and multicomponent data analysis. Chuck worked for 29 years as a geophysicist, and is now applying newly developed volume-based seismic attributes to data from a variety of geologic settings while completing his PhD studies.
