From a technical perspective, both are what we call extra-heavy oil, meaning that the density is very low. There's also a lot of sulphur in the oil, so it requires some additional processing. Refiners like those types of barrels because they tend to be cheaper than the light sweet oils that constitute the major benchmarks for the oil market. A lot of refinery capacity was first built in the U.S. and then in Asia to process those types of barrels.
Technically, they're very similar below ground. Above ground, of course, Canada is a much more stable environment. Our companies are doing a great job of developing the resource here. We're slowly lowering the greenhouse gas intensity of emissions. We're slowly developing indigenous partnerships, whereas obviously, as we've been discussing, there's still a lot of uncertainty about the political climate in Venezuela and the capacity of the industry to get back to where it was 20 years ago.
