The U.S. Geological Survey (USGS) has completed an assessment of the undiscovered oil and gas potential of the U.S. portion of the Michigan Basin. The assessed area includes the State of Michigan, as well as parts of Illinois, Indiana, Minnesota, Ohio, and Wisconsin. The assessment is based on the geologic elements of each total petroleum system (TPS) defined in the basin. These geologic elements include the hydrocarbon source rocks, reservoir rocks, and hydrocarbon traps. By using this geologic framework, the USGS defined 6 total petroleum systems and 13 assessment units (AUs) within the basin and estimated the quantity of undiscovered technically recoverable oil and gas resources within 9 of the 13 AUs. By using a geology-based assessment methodology, the U.S. Geological Survey estimated the following quantities of undiscovered, technically recoverable oil and gas resources in the U.S. portion of the Michigan Basin: (1) a mean of 990 million barrels of oil, (2) a mean of 11 trillion cubic feet of natural gas, and (3) a mean of 220 million barrels of natural gas liquids.
