Thanks to expanding heavy crude oil production in Western Canada’s oil sands in recent years and increased pipeline access from the region to the U.S. Gulf Coast, re-exports of Canadian heavy crude from Gulf Coast terminals set a record in 2023. With additional production gains on tap in the oil sands, it might seem natural to think that another re-export record is in the works for 2024. However, assuming the much-delayed Trans Mountain Expansion Project (TMX) does indeed start up this year — offering a vastly expanded West Coast outlet for oil sands production — last year’s re-export high might end up being a peak, at least for the number of years it takes for growth in Western Canadian heavy crude production to exceed the capacity of the TMX expansion. In today’s RBN blog, we take a closer look at TMX’s likely impact on Gulf Coast re-exports.
