Tom C. Clark,
Phillips Petroleum Company v. Oklahoma…
“ Phillips argues that it is not a purchaser but merely a producer; that unlike the situation in Cities Service, the order as applied to it lacks any connection with correlative rights, the interest of the public, monopolistic practices or discrimination. The distinction is without a difference: the connection between realized price and conservation applies to all production in the field, whether owners purchase from others or not, and whether they own pipe lines or not. ”
