There must be a ratio, but I don't know it. I know there are many more people employed in the service sector on an employment basis than in the exploration and production companies, but I'd have to defer to someone who knows that exact number.
In terms of types of jobs, there are just so many. There's construction, because we construct well sites; there's all kinds of labour around the rig itself; there are so many different services that show up there, from cementing to logging to monitoring of your drilling to the rig itself. There are so many different specialty services on a rig site. There are typically 50 to 100 people working on a rig at one time. There are all kinds of different qualifications, from labour all the way to people who are highly trained.
It's a bit tough to bring that down, but you're on to the point that is my current challenge in Quebec: to bring that point exactly down for people on the south shore.
