Western Canadian producers have been deeply impacted by lower crude oil prices and the demand-destroying effects of COVID-19. This past spring, oil production in the vast region dropped by an estimated 940 Mb/d, or as much as 20% from the record highs earlier this year. Taking that much production offline helped in at least one sense: it eased long-standing constraints on takeaway pipelines like Enbridge’s Canadian Mainline, TC Energy’s Keystone Pipeline, and the government of Canada’s Trans Mountain Pipeline. Production has been rebounding this summer, however, and there are indications that pipeline constraints may be returning and apportionment of uncommitted space on some pipes may again become a persistent issue. Today, we continue a review of production and takeaway capacity in Alberta and its provincial neighbors with a look at apportionment trends on the biggest pipelines.

Yup. Pigs are critical to the safety and integrity of pipelines. Some are your basic utilitarian pigs, while others are quite smart, if not downright cool. No, these are not the pigs down on the farm. Instead, these pigs are devices run through pipes to clean, inspect, and support “batching” on hydrocarbon pipeline networks. They help ensure the safe and efficient transportation of crude oil, NGLs, petroleum products, and natural gas through more than 2.5 million miles of pipeline in the U.S. If you’re interested in energy and energy delivery, you’ve gotta know about pigs, and that's just what we'll be discussing in today’s blog.

Pipelines are lifelines to refineries, steam crackers, and other consumers of energy commodities, and even the hint that a major pipeline may be shut down raises big-time concerns. For evidence, look no further than Enbridge’s Line 5, which batches light crude oil and a propane/normal-butane mix across Michigan’s upper and lower peninsulas and to points beyond. One of Line 5’s two pipes under the Straits of Mackinac is temporarily out of service, halving the 540-Mb/d pipeline’s throughput, and Michigan’s attorney general continues to pursue a lawsuit that, if successful, could be Line 5’s death knell. Enbridge also is facing a fight on its plan to replace the twin underwater pipes with a new, safer “tunnel” alternative. All of which raises the question, what would be the market effects if Line 5 is permanently closed? Today, we conclude a miniseries on one of the Upper Midwest’s most important liquids pipelines.

In May of this year, Western Canada’s oil production shut-ins due to weak demand and poor pricing were estimated to have peaked near 1 MMb/d, resulting in a 20% drop from the near-record production levels reached only a few months earlier. The magnitude of the production fall in such a short period of time caused a significant drop in the utilization of pipelines that transport crude oil from Alberta to other parts of Canada and the U.S. All of a sudden, pipelines that had been heavily rationing their capacity over the past couple of years to accommodate steadily rising production suddenly had ample spare capacity. With those supplies now on the road to recovery, pipelines have begun to fill some of that extra space and are moving toward rationing capacity once again. Today, we continue our review of Western Canadian production and takeaway capacity with a look at how this spring’s production cuts affected the region’s biggest pipelines.
