Cenovus Energy, Canada’s largest oil sands producer and operator, reported its third quarter financial and operational results on October 31. The company achieved record oil sands output in the quarter thanks to ongoing optimization and expansion work which built upon lower output in the prior quarter that was impacted by seasonal turnaround activities. Most of the company’s crude oil output is produced via thermal operations (SAGD — steam assisted gravity drainage) in which steam is injected into bitumen/heavy oil reservoirs with the heated material pumped to the surface for further processing. The company also has downstream refining assets located in Saskatchewan, Ohio and Wisconsin. Our summary is focused on the Canadian oil sands/heavy oil operations, with additional commentary regarding refining activities and the MEG Energy acquisition.
- Christina Lake – the company’s largest thermal oil sands producing asset, achieved record output of 251.7 Mb/d, versus 217.9 Mb/d in the second quarter, partly boosted by new production from its nearby Narrows Lake asset which is fed into the Christina Lake processing complex. Narrows Lake achieved first oil in July and is expected to ramp toward output of 20 to 30 Mb/d in 2026, increasing overall Christina Lake throughput.
- Foster Creek – by output, the company’s second largest oil sands site, produced 215.4 Mb/d, up from 186.1 Mb/d in the second quarter. Utilizing monthly output data from the Alberta Energy Regulator (AER) to August 2025, the third quarter average would yield record production of 220.0 Mb/d in September. Optimization work at Foster Creek is 98% complete with new steam generators completed and additional well pads planned for start up in 2026. The company is targeting additional growth of more than 30 Mb/d by 2027.
- Sunrise – ranked third in terms of the company’s Alberta oil sands output, reached 52.4 Mb/d versus 50.3 Mb/d in the prior quarter. Both quarters were impacted by turnaround activities. An additional well pad is being prepared for start up in the fourth quarter which will support production near current levels.
- Lloydminster Thermal – located in Saskatchewan, achieved 95.7 Mb/d versus second quarter output of 97.8 Mb/d.
- U.S. refining throughput of crude oil was reported at a record 605.3 Mb/d, achieving a 99% utilization rate, up from 553.4 Mb/d (90% utilization) in the prior quarter. On September 30, Cenovus closed the sale of its 50% working interest in WRB Refining LP, a joint venture with Phillips 66, which operates refineries located in Wood River, IL and Borger, TX, for cash proceeds of C$1.8 billion. The sale will result in a downward adjustment to the company’s average annual refinery throughput in the range of 53 Mb/d.
- MEG Acquisition - the company’s process to acquire rival oil sands producer MEG Energy is approaching the finish line as it has successfully warded off a bid from rival producer Strathcona Resources (see our blog Get Together). After upping its bid for MEG Energy in October to fend off Strathcona and work through two delays in a shareholder vote to approve the deal, a shareholder meeting is scheduled for November 6 which is expected to consent to the Cenovus takeover offer. MEG Energy operates its own Christina Lake oil sands asset, adjacent to Cenovus’s, with reported average production of 107 Mb/d (July/August) based on data from the AER.
With RBN’s expectation that Canadian crude oil production will rise in the range of 500 Mb/d by the end of 2030, Cenovus is a key component of this production expansion.
