Apportionment

Wider price discounts for Western Canadian heavy crude oil have been weighing on its oil producers for the past few months. This appears to be the result of a combination of weak refinery demand, rapidly rising oil production and insufficient oil takeaway capacity from Western Canada. A more permanent solution for wider discounts might be to increase pipeline export capacity to ensure that rising oil production has more options to reach markets. In today’s RBN blog, we consider the pending startup of the Trans Mountain Expansion Project (TMX) as a means to do just that.

The price discount for Western Canada’s benchmark heavy crude oil has seen yet another widening in the past few months. Increased pipeline access to the U.S. was believed to be the key to solving this problem in the long term, but more recent fundamental developments surrounding pipeline egress, refinery demand and increasing heavy oil supplies demonstrate that larger discounts can — and do — still happen. This problem could persist for several more months until a better balance is achieved in downstream markets. In today’s RBN blog, we discuss the latest drivers of the wider price discounts for Western Canada’s heavy oil. 

Since early this year, the Midland crude differential has continued to widen, trading one day last week at a discount of $15.75/bbl to West Texas Intermediate (WTI) at Cushing, the widest spread since August 2014 before settling back to $11.25/bbl on Monday. The wide price differential is a result of fast-growing production in the Permian and bottlenecked takeaway pipelines. But the trajectory of this increasing price spread has been anything but smooth. Lately, we have seen a blip in the price differentials right around the 19th or 20th of the month. In each of the last three months, for a short-lived 24 to 48 hours, the Midland-Cushing price differential has narrowed by $2/bbl or more as Permian shippers have gone on feeding frenzies. Today, we look at these brief upticks in pricing and the pipeline and trader mechanics behind them.

While recent analysis has raised concerns crude oil pipelines are running half empty the opposite is true for many of the nations’ refined product distribution pipes. Take the huge Colonial Pipeline system that delivers as much as 2.7 MMb/d of refined products from Gulf Coast refineries to destinations up the East Coast as far as New York. The southern stretch of the pipeline from Pasadena near Houston to Greensboro, NC has been running full since 2012 - meaning that shipper volumes are subject to rationing or apportionment. Today we start a two-part series explaining why the Colonial pipeline is so congested and how it operates.
