The ability to use steam-assisted gravity drainage is very specific to geology. Some parts of the oil sands can only be mined, because the resource is too close to the surface. We can't build up the pressure and heat that we need to actually get the oil to flow to the surface.
With respect to MEG Energy's environmental performance and competitive advantage, there are quite a few SAGD users across industry. The in situ industry is kind of the industry of the future. The vast majority of the oil sands resource will be developed with steam-assisted gravity drainage. We've been able to drive that line below the industry average through our use of cogeneration. We've made upfront capital-intensive investments in cogeneration—in eMSAGP, enhanced modified steam and gas push, and in eMVAPEX, the enhanced modified vapour extraction.
We're seeing more and more of those downhole technologies come into play, be it through solvent or non-condensable gas usage. A lot of our industry peers are starting to use those. Those are proprietary, so they're not necessarily shared in groups like COSIA, but we are seeing each of us individually develop those technologies and try to maximize resource extraction so that we can get as much as possible from the resource with as little environmental impact as possible.
