I, for reasons I can't explain, regularly like reading the news articles on oilprice.com
Originally, the US needed the pipeline to get more Canadian oil. We don't need that so much now.
Canada needs pipelines to get oil to market, and are selling at a discount.In the intervening years since TransCanada originally proposed Keystone XL, U.S. oil production has grown by more than 80 percent, from just over 5 million barrels per day to about 9.6 mb/d today. There has also been a massive buildout of oil pipelines in the U.S., taking crude from the Bakken and the Permian to refineries on the East and Gulf Coasts. The urgent need for Keystone XL is questionable.
Two other options besides Keystone.......For Canada, however, the need for pipelines is more evident than ever. Western Canada Select (WCS), a benchmark for heavy crude from Alberta, routinely trades at a discount to WTI (West Texas intermediary oil). However, that discount has worsened because of pipeline bottlenecks. Bloomberg Gadfly points out that there is a shortage of pipeline capacity from Canada equivalent to about 330,000 bpd this year, a deficit that will balloon to 700,000 bpd by 2019 as more oil sands projects come online at a time when all major pipeline projects have suffered from serious delays. WCS is now trading at a massive discount even to heavy crude from Mexico – the latter has a much easier time getting to refineries in Texas and Louisiana.
But don't need all three.The only options for Canada’s oil producers are the Trans Mountain expansion, which will triple the line’s existing capacity from 300,000 to 890,000 bpd, taking Alberta to Canada’s Pacific Coast and Enbridge’s Line 3 expansion to Wisconsin, which will boost the pipeline’s capacity and is much more likely to move forward. The third and last option for Alberta is Keystone XL
“We definitely need two of these pipelines by around 2025 and after that it depends on the supply outlook,” Mark Oberstoetter, an analyst with Wood Mackenzie, told Reuters earlier this year. “There’s not an evident need to get three or four pipelines built.”
