For some of them, they can be retrofitted. Some of the enhanced steam utilization technology, some of the technologies that address tailings waste, water waste, etc., those can largely be retrofitted. But many of the solvent-injection technologies, which are perhaps some of the largest plays in terms of the potential for both water savings and GHG emission reductions—in fact, we have one in our portfolio that's targeting emission reductions of about 70%—that will require new infrastructure and a new project to be developed. It would not be a retrofit application. Again, the time horizon, if you had all the capital at hand today, is that you're probably looking at three to five years before that project could have any substantial production, at a minimum.
