Oil Bottlenecks: Cushing Draws, Rail Jams, and Tight Physical Markets

Marcus Hayes

You know, if you spent any time watching physical oil markets lately, you have probably noticed that things are getting pretty wild out there. According to the latest Oil Market Report from the International Energy Agency, global oil inventories plunged by a massive ninety five million barrels in a single month. That is ninety five million barrels gone in August alone. And that supply squeeze pushed Brent crude prices surging right past one hundred and five dollars per barrel. Suddenly, refiners in the Atlantic Basin are scrambling, bidding up every physical North American barrel they can get their hands on.

And it does not stop overseas. If you look at the U.S. Energy Information Administration's Weekly Petroleum Status Report, their updated stock summary showed a surprise commercial crude draw of three point two million barrels. Down in Cushing, Oklahoma, which is the main pricing point for U.S. crude, inventories fell below twenty two million barrels. That is a really tight buffer, and it drove prompt West Texas Intermediate spreads into steep backwardation.

At the same time, up in Canada, Western Canadian Select differentials widened out to fifteen dollars and fifty cents under WTI. Why? Because seasonal maintenance in the Alberta oil sands choked off incoming diluent imports, leaving heavy crude stranded. Meanwhile, out in North Dakota, Bakken production is holding strong at around one point two million barrels per day. But with main pipelines running completely full, regional producers are getting pushed back into rail transloading hubs to move those extra physical barrels.

It really reminds me of talking with old commodity trading veterans who remember the sudden market pivots of past decades. When Cushing stocks drain overnight and an overseas crisis strikes, midstream operators do not have six months to wait on pipeline approvals. They have to shift from long term pipe storage strategies to loading spot rail cars in a matter of hours. It is fast, it is messy, and it completely reshuffles regional trade flows.

That brings us right to the regional bottleneck hubs, starting with Guernsey, Wyoming. Guernsey crude differentials recently strengthened to seventy five cents over Cushing. Industry analysis from East Daley Analytics points out that the Pony Express Pipeline is operating at one hundred percent utilization, pulling incremental crude from both the Bakken and the Powder River Basin straight south.

But here is where the plumbing gets tricky. To get crude from Guernsey down to the Saddlehorn Pipeline, it has to pass through the Cheyenne and Cowboy pipeline connectors. Cheyenne can handle one hundred and twenty thousand barrels per day, but Cowboy Pipeline is stuck at a bottleneck capacity of ninety five thousand barrels per day. Plains is actively working on expanding Cowboy to one hundred and twenty five thousand barrels a day, but until that expansion is finished, physical barrels are trapped behind that restriction.

This pipe friction comes right as active drilling in the Powder River Basin from operators like Anschutz and EOG is piling new production into Guernsey. So producers are forced to do the hard netback math, comparing pipeline transit against moving barrels by rail straight to the Midcontinent or down to the Gulf Coast.

And then, of course, there is Utah's Uinta Basin waxy crude. This oil is super unique. It turns solid like shoe polish at room temperature, but refiners on the Gulf Coast absolutely love it for their fluid catalytic crackers because it has almost zero sulfur and yields fantastic product expansion. In fact, according to trade reports, Uinta waxy crude has been fetching a premium of around three dollars per barrel over WTI, even as nearby Salt Lake City refineries ramp back up to ninety two percent capacity following fall maintenance.

The long term plan for Uinta crude was the proposed eighty five mile Uinta Basin Railway project, which carried one hundred and thirty thousand barrels per day of take or pay commitments. But with that rail line frozen in ongoing federal court litigation, producers cannot rely on new tracks anytime soon. Instead, they are sticking with the current playbook, using specialized heated and insulated coiled railcars to keep the wax liquid all the way down to the Gulf Coast. It just goes to show you, when market demand is strong enough, energy infrastructure always finds a way to move the barrel.
