Thank you.
You mentioned carbon capture and sequestration, which takes me to my second question for you, on R and D.
To what extent does your sector spend on R and D? I know there are federal, and I'm not quite sure whether there are provincial.... I'd be interested in knowing how important R and D is from your company's perspective, and how it is reflected in terms of how much money is spent on R and D, not only for more efficient ways of extracting the resource, but also for issues related to such things as the environment.
