I'm scratching deep to see if I can come up with anything new on the horizon, and in all honesty, I can't.
What I can say, though, is that with respect to research and development and new technologies, our industry, if it's anything, is taking the existing programs we have, whether they are engineering, mechanical, petroleum, or the trades, and giving people a solid depth of training in fulfilling those positions. Then they evolve as the industry evolves and they learn on the job.
I mean, you take a guy operating a control truck for a hydraulic fracturing job. He's got a hundred pieces of equipment on location, all tied in with pressure gauges and instrumentation. He's monitoring a 15,000 psi frac that is 3,000 kilometres below the surface of the earth. He didn't get that training in university and he didn't get it in college. He got it on the job. You don't just pick somebody off the street with no skills and put them there.
To answer your question, I can't name any one particular profession, but it's to build up what we have and we evolve from there.
