It looks like the USA is starting to fill the SPR, they purchased 3 million boe in May and plan to purchase more later on in the year. The EIA numbers are really all over the place and i don't know if that is just the way it is, or if it is designed to cause confusion. SRP releases, Big Imports, Gasoline Imports, etc, the energy matrix is quite complicated right now.
The transmountain is suppose to be in service in Q1, 2024 and this will mean the usa will have to get about 600,000 boe more from imports weekly or about 4 million boe/week.
SPR Purchases Link IMHO
