Crude Oil Feedstock

Canadian pipeline company (NYSE/TSX: ENB, HQ Calgary); operates the world's longest and most complex crude oil and liquids pipeline system, including the Enbridge Mainline network transporting ~3 million barrels per day of Canadian crude to US refineries. Enbridge's Line 5 through Michigan (under the Straits of Mackinac, Lake Michigan/Huron, challenged by Michigan government) carries ~540,000 bpd of crude and NGL critical for Ohio, Pennsylvania, and Ontario refineries. A Line 5 shutdown would severely curtail crude supply to Great Lakes region refineries. Enbridge acquired Dominion Energy Midstream (gas pipelines) and a 25% interest in the Mainline — one company carries ~65% of Canadian crude exports to the US.

One of the world's largest oil and gas companies; major US and global sulfur producer as a Claus Process refinery byproduct. Key US refining locations: Baytown, Texas (largest US refinery complex); Baton Rouge, Louisiana; Beaumont, Texas. Also major international refiner (Antwerp, Rotterdam). USGS listed as one of leading US recovered sulfur producers. Also holds 25% of Tengizchevroil (TCO) in Kazakhstan, making it indirectly a significant producer of high-sulfur crude and associated sulfur. Acquired Pioneer Natural Resources 2024 (~$60B), largest US oil deal since Exxon-Mobil merger.

World's largest oil company by revenue and production. Also the Middle East's largest sulfur exporter: Aramco exports ~3.5M MT of elemental sulfur/year via its trading subsidiary Aramco Trading Company. Sulfur is a mandatory Claus Process byproduct at Aramco's Ras Tanura, Yanbu, and Jizan refineries and gas plants — recovered to comply with environmental regulations and sold globally as a commodity. Saudi Arabia accounts for ~8% of global sulfur production and a larger share of global sulfur exports. Middle East overall (including Aramco) = ~30% of global sulfur supply.

Canada's largest integrated energy company; one of the world's largest oil sands operators. Produces 800,000+ MT/year of marketable elemental sulfur as a mandatory byproduct of oil sands bitumen upgrading. Canada's oil sands bitumen contains ~5% sulfur by weight — at 3.7M barrels/day of extraction, Alberta oil sands theoretically contain 8.3M MT sulfur/year (though only ~3M MT/year is captured and marketed). Suncor ships formed sulfur via rail to Port of Vancouver, B.C. for export to China, South Africa, and Australia. Suncor is also Canada's largest fuel retailer (Petro-Canada brand).

Largest Russian oil company; petcoke producer from Komsomolsk-on-Amur (260,000 t/yr) and Novokuibyshevsk refineries; subject to US/EU OFAC sanctions since 2022; primarily domestic Russian market supply.

TC Energy Corporation (Calgary, Alberta; TSX/NYSE: TRP) is one of the largest operators of underground natural gas storage in the northeastern US through its Columbia Gas Transmission subsidiary. Columbia Gas Transmission operates approximately 30 underground storage fields in West Virginia, Ohio, Pennsylvania, Virginia, and Kentucky — the largest concentration of UGS fields by count in the US. These fields have combined working gas capacity of approximately 600 Bcf, serving the Northeast and Mid-Atlantic markets. TC Energy's storage is primarily in depleted gas reservoir fields in the Appalachian Basin. The Columbia storage system plays a critical role in winter peak supply for the most densely populated region of the US. In addition, TC Energy's Canadian Mainline pipeline system includes storage fields in Ontario (Dawn Hub — the most liquid natural gas trading hub in Canada).

Mexican state oil company; emerging petcoke exporter; Olmeca (Dos Bocas) refinery shipped first petcoke cargo Jan/Feb 2024 (2-2.5M t/yr capacity); owns Deer Park TX refinery (from Shell, 2021); planned coker units at Tula and Salina Cruz could add 3-5M t/yr total.

Canada's largest privately-owned refinery operator. Its Saint John, NB refinery (320,000 bpd capacity) is the single most important external source of heating oil for the US Northeast, exporting over 80% of its output to the United States.

One of the largest independent petroleum refiners in the US, operating six refineries with ~1 million bpd combined capacity. Its East Coast refineries — Delaware City, DE (180,000 bpd) and Paulsboro, NJ (180,000 bpd) — are among the last significant refineries serving the Northeast heating oil market directly.
