The Seaway Crude Pipeline System (SCPS), commonly known as the Seaway Pipeline, is an oil pipeline system which transports crude oil between Cushing, Oklahoma and Freeport, Texas, and through the Texas City, Texas Terminal and Distribution System on the Gulf Coast of the United States. The Seaway is an important crude oil transfer link between two petroleum regions within the United States. [1]
Although Seaway shipped oil north (to Cushing) for many years, in June 2012 the flow of the system was reversed to ship oil south (out of Cushing).
The Seaway Pipeline was originally built by a consortium of oil industry firms formed in 1974 named Seaway Pipeline, Inc. for transferring (then) cheap foreign oil from Texas ports to refineries in the Midwest. After two years of construction, the system became operational on 23 November 1976, and pumped crude oil north until 1982. [2]
In 1984, the other consortium members were bought out by Phillips. Seeking to capitalize on the pipeline's location to gather raw natural gas in Oklahoma and Texas for transport to the company's refinery complex at Sweeny, Texas, and other refineries near Houston, Phillips converted the system to ship natural gas south instead of shipping crude oil north. Phillips called that arrangement the "Seagas Pipeline". [2]
In 1995, Atlantic Richfield bought a 50% interest from Conoco through a subsidiary (ARCO Pipeline), and the system was converted from shipping natural gas south to shipping oil north to Cushing in 1996.
In 2000, Texas Eastern Products Pipeline Company (TEPP or TEPPCO), an indirect subsidiary of Duke Energy through TEPPCO Partners, bought the stock of ARCO Pipeline, acquiring their 50% interest in the system, and became the primary operator. [3]
In 2005, Texas Eastern Products Pipeline, was acquired by Enterprise Products Partners L.P. in 2005, and Enterprise Products became the system operator with a 50% stake. [4]
In late 2011, Canadian pipeline company Enbridge bought Conoco's remaining 50% interest in the company for $1.15 billion. The Seaway Crude Pipeline Company LLC (a joint venture between Enterprise Products and Enbridge) became the pipeline's operator. [5]
In late May 2012, the Seaway's flow was reversed, and crude began arriving at Freeport on 6 June 2012. [6] [7]
On January 11, 2013, the Seaway's capacity was increased to 400,000 barrels per day (64,000 m3/d). [8]
On January 30, 2017, a Texas Department of Transportation crew accidentally dug into the Seaway Pipeline near Blue Ridge, Texas, causing a large spill. [9] On January 30, 2017, a road crew punctured the Seaway pipeline near Dallas. Two days later, it was unclear how much oil had spilled over the nearby Highway 121. After the incident, supply concerns reportedly helped push oil prices 2% higher. [10]
As of June 2012, the entire system is 670 miles (1,080 km) long, of which, 500 miles (800 km) are in the 30 inches (760 mm) long-haul (Cushing to Freeport) portion of the pipeline. The system was then capable of carrying approximately 180,000 barrels per day (29,000 m3/d) of oil.
Plans have been announced [11] to increase Seaway's capacity to 400,000 barrels per day (64,000 m3/d) in 2013 (completed as of 11 January 2013) and, in 2014, adding 450,000 barrels per day (72,000 m3/d) additional capacity via a "twin" long-haul pipeline. As well as for an 85 miles (137 km) lateral to the ECHO crude storage facility in southwest Houston and the Port Arthur/Beaumont refining complex.
Several competing pipelines between Cushing and the Houston region have been proposed over the years, no other directly competing pipeline has yet been built. Although there is one larger pipeline which also connects the midwest with the Gulf Coast, the Capline, but which bypasses Cushing. The 40 inches (1,000 mm) Capline has been pumping offshore oil north from Louisiana to Patoka, Illinois since the 1960s. [12]
However, planning for Phase 3 (a.k.a. the "Southern Leg", "Cushing MarketLink", or "Gulf Coast Pipeline Project") of the proposed Keystone XL show that it would run 435 miles (700 km) from Cushing to Nederland, Texas near Port Arthur, where it could tie into an existing 47 miles (76 km) pipeline to the Houston area. [13]
Cushing is a city in Payne County, Oklahoma, United States. The population was 7,826 at the time of the 2010 census, a decline of 6.5% since 8,371 in 2000. Cushing was established after the Land Run of 1891 by William "Billy Rae" Little. It was named for Marshall Cushing, private secretary to U.S. Postmaster General John Wanamaker.

The Enbridge Pipeline System is an oil pipeline system which transports crude oil and dilbit from Canada to the United States. The system exceeds 5,000 kilometres (3,100 mi) in length including multiple paths. More than 3,000 kilometres (1,900 mi) of the system is in the United States while the rest is in Canada and serves the Athabasca oil sands production facilities. Main parts of the system are 2,306-kilometre-long (1,433 mi) Canadian Mainline and 3,057-kilometre-long (1,900 mi) Lakehead System. On average, it delivers 1.4 million barrels per day of crude oil and other products to the major oil refineries in the American Midwest and the Canadian province of Ontario. The Canadian portion is owned by Enbridge, while the U.S. portion is partly owned by that company through Enbridge Energy Partners, LP, formerly known as Lakehead Pipe Line Partners and Lakehead Pipe Line Company.
Petroleum production in Canada is a major industry which is important to the economy of North America. Canada has the third largest oil reserves in the world and is the world's fourth largest oil producer and fourth largest oil exporter. In 2019 it produced an average of 750,000 cubic metres per day (4.7 Mbbl/d) of crude oil and equivalent. Of that amount, 64% was upgraded and non-upgraded bitumen from oil sands, and the remainder light crude oil, heavy crude oil and natural-gas condensate. Most of Canadian petroleum production is exported, approximately 600,000 cubic metres per day (3.8 Mbbl/d) in 2019, with 98% of the exports going to the United States. Canada is by far the largest single source of oil imports to the United States, providing 43% of US crude oil imports in 2015.
Enterprise Products Partners L.P. is an American midstream natural gas and crude oil pipeline company with headquarters in Houston, Texas. It acquired GulfTerra in September 2004.

The Enbridge Northern Gateway Pipelines were a project to build a twin pipeline from Bruderheim, Alberta to Kitimat, British Columbia. The eastbound pipeline would have imported natural gas condensate and the westbound pipeline would have exported diluted bitumen from the Athabasca oil sands to a marine terminal in Kitimat for transportation to Asian markets via oil tankers. The project would have also included terminal facilities with "integrated marine infrastructure at tidewater to accommodate loading and unloading of oil and condensate tankers, and marine transportation of oil and condensate." The CA$7.9 billion project was proposed in mid-2000s and has been postponed several times. The proposed project would have been developed by Enbridge Inc., a Canadian crude oil and liquids pipeline and storage company.
Western Canadian Select (WCS) is a heavy sour blend of crude oil that is one of North America's largest heavy crude oil streams and, historically, its cheapest. It was established in December 2004 as a new heavy oil stream by EnCana, Canadian Natural Resources, Petro-Canada and Talisman Energy. It is composed mostly of bitumen blended with sweet synthetic and condensate diluents and 21 existing streams of both conventional and unconventional Alberta heavy crude oils at the large Husky Midstream General Partnership terminal in Hardisty, Alberta. Western Canadian Select—the benchmark for heavy, acidic crudes—is one of many petroleum products from the Western Canadian Sedimentary Basin oil sands. Calgary-based Husky Energy, now a subsidiary of Cenovus, had joined the initial four founders in 2015.
