Abstract:
Much of the currently productive oil and gas acreage in the United States has been leased previously and generated some prior natural gas production. Consequently, the chance that a given parcel of productive land has been subject to some prior commitment by a producer to interstate commerce is quite likely. This raises the question of whether the prior dedication of natural gas to interstate commerce obligates the current producer to sell to an interstate pipeline or price his gas at a less favorable regulated price. The Natural Gas Policy Act of 1978 greatly reduced this burden, but it did create some interpretative problems of its own, which this Note attempts to resolve.
