I don't think Keystone XL is going to happen. Far too much CAPEX was consumed by Government delays, and (probably taxpayer funded) environmental groups suing over every thing that moved and some things that didn't (plants), but could be avoided. At some point, unlike government, you have to see results when you are a billion dollars or more into a project, and Biden nuked that.
Funny, though, how crude keeps being delivered by trains, but there has been no whining about that since Biden killed the pipeline.
