NGL Pipelines & Services
The Company’s NGL Pipelines & Services business segment includes its natural gas processing plants and related NGL marketing activities; approximately 16,700 miles of NGL pipelines; NGL and related product storage facilities; and 14 NGL fractionators. This segment also includes its import and export terminal operations. At the core of its natural gas processing business are 24 processing plants located across Colorado, Louisiana, Mississippi, New Mexico, Texas and Wyoming. Natural gas produced at the wellhead (especially in association with crude oil) contains varying amounts of NGLs. Once the mixed component NGLs are extracted by a natural gas processing plant, they are transported to a centralized fractionation facility for separation into purity NGL products. Once processed, this natural gas is available for sale through its natural gas marketing activities. Its NGL marketing activities generate revenues from the sale and delivery of NGLs it takes title to through its natural gas processing activities and open market and contract purchases from third parties. Its NGL marketing activities utilize a fleet of approximately 670 railcars, the majority of which are leased from third parties.
The Company’s NGL pipelines transport mixed NGLs and other hydrocarbons from natural gas processing facilities, refineries and import terminals to fractionation plants and storage facilities; distribute and collect NGL products to and from fractionation plants, storage and terminal facilities, petrochemical plants, export facilities and refineries, and deliver propane to customers along the Dixie Pipeline and certain sections of the Mid-America Pipeline System. Revenues from its NGL pipeline transportation agreements are based upon a fixed fee per gallon of liquids transported multiplied by the volume delivered. Certain of its NGL pipelines offer firm capacity reservation services. It collects storage revenues under its NGL and related product storage contracts based on the number of days a customer has volumes in storage multiplied by a storage fee. In addition, it charges customers throughput fees based on volumes delivered into and subsequently withdrawn from storage. Its principal NGL pipelines include Mid-America Pipeline System, South Texas NGL Pipeline System, Seminole Pipeline, Dixie Pipeline, Chaparral NGL System, Louisiana Pipeline System, Skelly-Belvieu Pipeline, Promix NGL Gathering System, Houston Ship Channel pipeline, Rio Grande Pipeline, Panola Pipeline and Lou-Tex NGL Pipeline. It operates its NGL pipelines with the exception of the Tri-States pipeline.
The Company’s NGL operations include import and export facilities located on the Houston Ship Channel in southeast Texas. It owns an import and export facility located on land it leases from Oiltanking Houston LP. Its import facility can offload NGLs from tanker vessels at rates up to 14,000 barrels per hour depending on the product.
