Downstream: Refining and Marketing

While refining is a complex process, the goal is straightforward: to take crude oil, which is virtually unusable in its natural state, and transform it into petroleum products used for a variety of purposes such as heating homes, fueling vehicles and making petrochemical plastics.

Wolcott, Marion Post. Barnsdall oil refinery. Kansas, 1941.

A number of processes are involved in refining depending on the wanted end product. Hydrotreating is used to remove unwanted elements, such as sulphur and nitrogen from hydrocarbons; cracking breaks molecules into smaller fragments to produce gasoline and other lighter hydrocarbons. The gases produced by cracking are used to create other products like synthetic rubber and plastics. When making gasoline, refiners need high octane numbers to prevent engine knocking. Despite knowing the dangers of lead, tetraethyl lead was added to gasoline in the United States in the 1920s in order to increase the octane. Since the U.S. government banned lead in vehicle gasoline in 1996 as part of the U.S. Clean Air Act, refineries use alkylation and reforming to develop high-octane gasoline.

Biden administration, in its last days, proposes new protections for Arctic Alaska land

Lakes and connecting streams in the northeastern part of the National Petroleum Reserve in Alaska, June 2014.

Four days before President Joe Biden is set to leave office, his administration recommended that about 3 million more acres in Alaska's western Arctic be protected from development and issued a guideline, effective immediately, requiring additional protections for traditional Native subsistence harvests of fish, caribou and other resources.

The new recommendations and guidance, which apply to the 23-million-acre National Petroleum Reserve in Alaska, run counter to President-elect Donald Trump's expressed plans to expand oil drilling in the Arctic and elsewhere and to overturn Biden administration environmental policies more broadly. 

The recommendations for additional land to be protected as part of what are termed "special areas" and the guidance for elevating the importance of subsistence and tribal consultation could be ignored or scrapped by the incoming Trump administration.

The northeastern part of the reserve is the area considered most likely to hold oil and where development has spread in recent years. There is already production in that area, and the most notable production expected in the future is from ConocoPhillips' Willow project. Willow won Biden administration approval in 2023. Production is expected to start by the end of the decade and peak at 180,000 barrels per day; current production from all North Slope fields amounts to less than 470,000 barrels per day. 

Like the existing Teshekpuk special area, which holds important habitat for caribou, fish and migratory birds, the village of Nuiqsut is in the general area of the reserve's northeastern corner, where new oil development has occurred. Nuiqsut is so close that oilfield infrastructure can be seen from the village. 

Pipelines extend across the landscape outside Nuiqsut, Alaska, May 2019. 

"But at the same time, I think we and our partners have also made it abundantly clear that we're going to keep fighting, and keep fighting for protections in the Western Arctic," she said.
