Michigan--Oil & Gas

摘要

As in other oil- and gas-producing regions of the country, the practice of hydraulic fracturing (tracking) is receiving heightened scrutiny from certain groups and Michigan regulators concerned about the potential migration of gas and the environmental impact of fracturing fluids used in the process. Fracking has been widely utilized in Michigan for nearly 30 years, primarily in the Antrim shale formation in Michigan's Lower Peninsula, with approximately 12,000 wells having been tracked. More recently, the fracking technique has begun to be expanded into the substantially deeper Collingwood formation with horizontal wells.
