Links for Oil Rig websites

Hey guys,

I've been going around Alberta for two days now handing out resumes to oil rig companies in hopes of getting a job as a leasehand. I haven't heard any call backs so I was wondering if I missed any companies that I could've applied. Would any of you know a website that lists the active oil rig companies so I can look at their address and also apply online? I'm trying to get into a drilling rig if possible.

I'm planning to go to Fort McMurray as well to apply but I have no clue where to apply there so I'm hoping there's a website as well that I can look into that lists companies in that place.

Also, would getting into a drilling rig be harder rather than applying for service rig?

Thanks!

P.S. I already have all my tickets needed so I'm sure that's not it.
