Fracking in Montana occurs throughout the state, although there is a concentration of gas and oil fields in the northern portion of the state. The Bakken Shale Formation is one of the areas of current exploration. Like many other states, Montana requires the disclosure of the contents of fracking fluid, although companies can apply for a trade secret exemption to this requirement.
The Department of Natural Resources and Conservation Board of Oil and Gas is responsible for overseeing fracking in the state.
