Oneok Partners LP is holding an open season through Dec. 17 for its 600-mile Bakken Natural Gas Liquids (NGL) Pipeline, which would transport unfractionated NGLs from the Bakken Shale in the Williston Basin to an interconnection with the partnership’s 50%-owned Overland Pass Pipeline in northern Colorado. The Bakken NGL Pipeline is under construction and is expected to be in service during the first quarter. In July Oneok said it would expand the project with additional pump stations in a project to be completed during the third quarter of 2014.
