The 102-mile, 18-inch diameter Canyon Chief pipeline delivers natural gas from the Devils Tower spar to the Mobile Bay processing plant in Coden, Ala. The pipeline began operating in May 2004.

Houston Office

Our Houston office is home to Transco and our deepwater services group. Approximately 600 people work at this office. Williams has had a major presence in Houston since 1995.

Markham

The Markham complex has two facilities. The first one is a separation and dehydrating plant that removes water and condensate from natural gas. It opened in the early 1970s. The second facility is a new cryogenic natural gas processing plant that began operating in 2001. It can process 300 million cubic feet per day.

Canyon Station

Canyon Station is a fixed-leg platform in 300 feet of water in East Main Pass Block 261, approximately 60 miles south of Mobile, Ala. It is designed to treat, process and handle up to 500 million cubic feet of natural gas per day. The platform commenced operations in July 2002.

Devils Tower

The Devils Tower spar is a floating production system located in 5,610 feet of water at Mississippi Canyon Block 773, approximately 150 miles southwest of Mobile, Ala. The facility is owned by Williams, operated by ENI, and capable of producing 60,000 barrels of oil per day and 60 million cubic feet of natural gas per day. It began operating in May 2004.

Galveston A244

Galveston A244 is a shallow-water junction platform that supports oil and gas production from the Boomvang, Nansen and Gunnison fields. Three of Williams’ offshore pipelines are connected to this facility.

Geismar

The Geismar, La., olefins production plant is located south of Baton Rouge. It can produce up to 1.3 billion pounds of ethylene per year. Williams operates the plant and has an 83-percent ownership interest.

Gunnison

The 96-mile, 18-inch diameter Gunnison pipeline delivers oil from Garden Banks Block 668 to Williams’ shallow-water platform at Galveston A244. The line became operational in December 2003. Capacity is approximately 84,000 barrels per day.

Mobile Bay

The Mobile Bay natural gas processing plant is located in Coden, Ala. Total processing capacity is almost 700 million cubic feet per day. The plant opened in 1999.

Mountaineer

The 117-mile Mountaineer oil pipeline is a combination of 18- and 20-inch-diameter pipe. It delivers oil from the Devils Tower spar to a third-party (Empire) terminal near Venice, La.

North Padre Island

North Padre Island is a 40-mile offshore gathering system that delivers natural gas into Williams’ Transco intrastate pipeline. It consists of 10-, 16- and 20-inch diameter pipe. Capacity is 200 million cubic feet per day.

Williams is a leader when it comes to gathering and processing natural gas. The services we provide help bring supplies of natural gas into the marketplace for the nation's energy needs. Our major Gulf Coast facilities are located onshore and offshore, from North Padre Island, Texas to Mobile, Ala.

Seahawk

Seahawk is a 114-mile offshore gathering system that collects natural gas from the Nansen and Boomvang fields. First deliveries of gas were received in January 2002. Total capacity is 360 million cubic feet per day.

Mustang Island

Mustang Island is a 50-mile gathering system located on- and offshore near Corpus Christi. It consists of 12-, 16- and 20-inch diameter pipe, delivering natural gas to a third-party pipeline. Capacity is 200 million cubic feet per day.

Discovery

The Discovery system consists of a 105-mile, 30-inch diameter mainline pipe and 168 miles of gathering laterals. The mainline was placed into service in late 1997 and has a design capacity of 600 million cubic feet of natural gas per day. Williams owns a partial interest in Discovery and operates its facilities.

Other Discovery facilities:

The Paradis, La., facility fractionates 42,000 barrels per day of natural gas liquids. It is located about 25 miles west of New Orleans.
The Larose, La., facility processes 600 million cubic feet of natural gas per day. It is located 35 miles south of New Orleans.
The Tahiti Lateral, a 16-inch gas gathering export pipeline, began flowing in May 2009. The lateral begins at the Tahiti spar located in Green Canyon 641 and terminates at a subsea connection located near the Frontrunner spar in Green Canyon 294. The 33-mile pipeline was installed in water depths of 2,700 to 3,800 feet.

Black Marlin

Black Marlin is a 16-inch natural gas gathering system originating offshore at High Island 136, transporting natural gas into the Texas City, Texas area. The Black Marlin facility in Texas City separates the condensate from the gas and stores this material in bulk storage tanks until it is transferred to tank trucks. The pipeline-quality natural gas is delivered to local industry in the Texas City area. The facility throughput capacity is 228 MMcfd.

Transco

The 10,500-mile Transco pipeline system transports natural gas from the Gulf Coast to northeastern and southeastern states. Total delivery capacity is approximately 8.4 million dekatherms.

Banjo

Banjo is a 56-mile offshore gathering system that collects oil from the Nansen and Boomvang Fields. First deliveries of oil were received in January 2002. Total capacity is 70,000 barrels per day.The name Banjo is an acronym for the Boomvang And Nansen Joint Oil System.

Bass Lite

A 60-mile gas gathering pipeline from Williams’ Devils Tower to the Bass Lite Field in Atwater Valley Block 426 was completed in first-quarter 2008 and began receiving first production the same quarter. The pipelines were installed in water depths of more than 6,000-feet.

Blind Faith

Williams recently installed two deepwater export pipeline laterals in more than 5,000 feet of water in the Gulf of Mexico for the Blind Faith project. Williams extended its Canyon Chief gas gathering system and Mountaineer crude oil pipeline by 37 miles each to transport oil and gas production from the Blind Faith Field. The Blind Faith discovery is located in approximately 7,000 feet of water at Mississippi Canyon blocks 695 and 696.

Perdido Norte

Pipeline construction began on Williams' 184-mile Perdido Norte system in first-quarter 2008. The pipelines extend to some of the deepest depths thus far in the Gulf of Mexico - approximately 8,300 feet of water. This new infrastructure is being built to gather the future production in the Perdido development area. The project includes 107 miles of natural-gas gathering pipeline, an expansion of Williams' Markham, Texas, processing plant and a 77-mile crude-oil transportation system.
