Market Access

Eastern Access

Line 9, an 832-kilometre (517-mile), 30” pipeline, transports crude oil from Sarnia, Ontario to Montreal, Quebec with an average annual capacity of 300,000 bpd. Enbridge continues to work with stakeholders to ensure safe and reliable delivery of crude oil to refineries in Eastern Canada.

Southern Access Extension

The Southern Access Extension Pipeline (SAX), a 270-kilometre (168-mile), 24” pipeline, transports crude oil from the Enbridge Flanagan Terminal near Pontiac, Illinois, to Patoka, Illinois. Since its in-service date in January 2016, the pipeline has provided customers with timely, economical and reliable transportation service to the strategic Patoka hub. SAX has an average annual capacity of 300,000 bpd and has expansion capability of 100,000 bpd for incremental access to the Patoka market.

Spearhead Pipeline

The Spearhead Pipeline is a 973-km (583-mile) pipeline comprised of 22” and 24” sections. It transports crude from the Enbridge Flanagan Terminal near Pontiac, Illinois to Enbridge’s Cushing Terminal in Cushing, Oklahoma. The capacity of the Spearhead pipeline is 193,000 bpd and one midpoint injection location at Key Station near the Platte Salisbury Terminal is available for limited capacities of crude.

U.S. Gulf Coast Access

Together, the Flanagan South Pipeline and the Seaway Pipeline System allow crude oil transported on the Enbridge Mainline system to access key U.S. Gulf Coast refining centers in Houston and Port Arthur, Texas. The Flanagan South Pipeline, a 954-kilometre (593-mile), 36” interstate crude oil pipeline that originates at the Enbridge Flanagan Terminal in Illinois and terminates in Cushing, Oklahoma, came into service in Q4 2014 and has an average annual capacity of 585,000 bpd.

The Seaway Pipeline system has an annual average capacity of 950,000 bpd and consists of two 846-kilometre (526-mile), 30” pipelines between Cushing, Oklahoma and the Freeport, Texas area that deliver into Jones Creek Terminal. The pipelines can deliver into Freeport and Texas City docks or the ECHO Terminal as well as continuing on to Beaumont/Port Arthur where the Seaway system connects to three terminals: Sunoco Nederland, Enterprise Beaumont Marine West and Phillips 66 Beaumont.

Enbridge continues to evaluate growth opportunities to expand capacity into the U.S. Gulf Coast. Expansions of the Flanagan South Pipeline and Seaway Pipeline can create up to 250,000 bpd of incremental access into the U.S. Gulf Coast market.

The Gray Oak pipeline is a 1,368-kilometre (850-mile) pipeline with an average annual capacity of 900,000 bpd stretching from the Permian basin to the U.S. Gulf Coast.

Once completed, it will connect production in the Permian and Eagle Ford to market centers in Corpus Christi, Sweeny and Freeport, Texas. The first stage of the project came into service in November 2019 and it is expected that Gray Oak pipeline will be fully in service by Q2, 2020.

SPOT and Texas COLT

Enbridge, through the Seaway Pipeline System, has two existing docks for export on the Gulf Coast at Freeport and Texas City. Freeport has a draft of 42 feet and can load at 20,000 barrels per hour and Texas City has a draft of 45 feet and can load at 35,000 barrels per hour. Texas City also has the capability to partially load a VLCC. Enbridge has negotiated an option to buy a portion of the Seaport Oil Terminal (SPOT). SPOT will provide direct loading capabilities into VLCCs which will provide a more efficient export solution. With a design loading rate of 85,000 barrels per hour, SPOT will be able to fully load a VLCC in 24 hours. SPOT is expected to receive permits in 2020 and be in service in 2023. Texas COLT will remain an option to be pursued should the market demand warrant.
