You know what, I've got it.
There's one thing I want to really try to clarify here. Everybody talks about shale gas. Actually, it's always all natural gas, but we find it in different formations, one of them being shale. From surveys that we've developed over the years, we realize that people really don't understand the difference. It's all natural gas; it simply comes from different formations.
That said, the technologies that we've developed, essentially for 60 or 70 years, have clearly identified significant pools of resources. The Pembina, the Cardium, and the Viking have all been well established.
The technology we've developed here in Canada is taking us below ground, beyond those conventional pools, and into the outer reaches of those same formations, and it's allowing us to steer into them with a directional drilling piece in combination with the hydraulic fracturing. These types of formations are found in vast quantities, not only in Canada but in China and in Russia, obviously, and different parts of the world.
There again, to go back to the high levels of collaboration between the services sector and the producing sector, we have a unique environment where I honestly believe we are leaders in this area. That's what's generating a lot of interest by foreign investors and other countries, because they have these resources under their feet and we've developed a technology to get at them safely and efficiently. That opens those doors for export potential for Canadian skills, labour, manufacturing, and product development.
