Thanks for the question, Phil. We continue to see record performance out of Kearl based on our supplemental crushing capacity that we have discussed in the past and other enhancements and reliability. And so that gives us great confidence in the assets productive capability. And moreover, as we've announced last quarter, we moved to 1 turnaround starting this year from 2 previously, which a key driver for us increasing our 2021 guidance to 265,000 barrels a day. A target, and as I just mentioned, we remain very confident in achieving given the continued strong performance through the third quarter and now into the fourth quarter. So beyond the 265,000 barrels a day level, we've got other low-cost projects to get to the 280,000 barrel a day level over the next couple of years, including plant debottlenecking, enhanced mine planning, bitumen recovery as well as some digital initiatives. You may recall at our previous Investor Day, we outlined that path to 280,000 barrels a day with Kearl reaching 270,000 barrels a day in the 2023 to 2024 time frame and ultimately to 280,000 barrels a day by 200 -- by 2025. We still see a progressive path. But as evidenced by our recent performance and our track record of continued improvements, I fully expect that we will do better than that 2025 time line. At our upcoming Investor Day in March, we'll give more information on that. But again, I expect that we'll be well ahead of that earlier time line. And I'd also note that as we continue to debottleneck Kearl and really put more barrels over a relatively high fixed cost asset base, we also expect to continue to drive down our overall unit cost. We are only partway through the ramp-up of our autonomous haul truck program, and we talked about realizing a USD 1 per barrel saving from the full rollout, which we expect to achieve over the next 2 years. So in addition, we see a number of opportunities to apply digital solutions more broadly at Kearl, which include drones, other optimization technologies with an overall objective to continue to drive that cost not only the $20 per barrel, but even lower beyond that. Thanks for that question, Phil.
