In July 2026, U.S. imports of crude oil from Venezuela averaged 701,000 barrels per day (b/d), the most since May 2017, before decreasing to 655,000 b/d in August, according to data published in our Petroleum Supply Monthly.

Crude oil imports from Venezuela started the year at 200,000 b/d and have steadily increased most months this year. Increased imports from Venezuela are supported by high crude oil demand from U.S. refineries because of high global refinery margins and the easing of U.S. government restrictions on purchases from the country. Many refineries on the U.S. Gulf Coast (PADD 3) are configured to process heavy sour crude oil grades, such as those from Venezuela.

According to data from Vortexa, the majority of

Data source: U.S. Energy Information Administration, Petroleum Supply Monthly

Particularly high refinery margins for distillate fuel oil and jet fuel have contributed to shifts in the refinery yields of major products in 2026. Data from our latest Petroleum Supply Monthly—which includes data through August 2026—indicate refinery yields of gasoline have decreased significantly this year to support increased production of distillate fuel oil and jet fuel, sometimes referred to as middle distillates due to their relative cut points in the oil refining process.

Petroleum refinery yields represent the share of a specific fuel that is produced from each barrel of crude oil a given refinery (or group of refineries) processes. The U.S. refining fleet tends to have a strong refinery yield of gasoline—typically between 45%–50%. In general terms, for every

MIT scientists have challenged two decades of conventional thinking by discovering that flexible molecular connections, rather than rigid ones, can unlock entirely new ways to arrange nanoparticles. The breakthrough could lead to a new generation of designer materials with unusual properties and applications in electronics, medicine, and energy.
