A proposed pipeline from Canada’s oil sands to refineries along the Gulf of Mexico would help “essentially eliminate” U.S. oil imports from the Middle East in a decade or two, according to a new study commissioned by the Department of Energy.

Oil deliveries from the $7 billion pipeline, combined with a projected drop in U.S. fuel demand, would potentially turn the United States into a net exporter of products like gasoline, jet fuel and diesel, said the report, called “Keystone XL Assessment.”

The Obama administration is divided over Keystone XL, a project that could ease reliance on oil from politically unstable regions, but boost dependence on Canadian oil sands, a crude that many environmental groups oppose.
