Operations

From Fort McMurray, Canada, to the deepwater Gulf of Mexico, and from Big Piney, Wyo., to Tunkhannock, Pa., we're focused on running large-scale assets and running them safely and reliably. Our network includes:

• Gas processing capacity of approximately 6.6 billion cubic feet of gas per day
• Annual natural gas liquids production of more than 200,000 barrels per day
• More than 10,000 miles of oil and gas gathering pipelines with inlet capacity of 10.6 billion cubic feet of gas per day and 475,000 barrels of oil per day
• Approximately 1,000 miles of NGL transportation pipelines with nearly 200,000 barrels per day of capacity
• Approximately 21 million barrels of NGL storage capacity
• Innovative deepwater infrastructure - strategic hubs

Note: Most of these assets are owned by Williams Partners L.P. (NYSE:WPZ), one of the largest energy master limited partnerships in the country. They also reflect 100 percent of equity investments. Williams owns approximately 75 percent of Williams Partners, including the controlling general partner interest.
