interesting comments - age distribution isn't something i'd though would of mattered much.
would it be possible to estimate the magnitude of this problem, and how it could impact future oil supplies (you did mention the 'now down, up later' aspect, but given that the raw numbers seem to indicate a rough balance, how large do you think the change could be?

Second, the graph is talking about changes in peak capacity of various projects, not changes in the date of arrival of that peak amount - wouldn't a lack of personal only effect the date at which the field is fully developed, and leave the peak extraction amount roughly untouched?

In either case the Hubert curve, which everyone likes to analyze oil production with, relys on the aggregate average of many oil fields, and as such the production profile from any individual field shouldn't significantly affect the nature of the curve, or predictions made from it.

what about in Geology? Is there still a need? My daughter is majoring in Geology, but she won't finish for 2 more years.
I am not sure, but I think she has a good future!

I can't guarantee your daughter an oil job, of course, but the industry isn't going to stop recruiting and training geoscientists (the preferred term nowadays) any time soon. She's probably hit the late-world-plateau time window just about right.

If she really wants to work in the oil business, it would help to study some or all of sedimentology, geoacoustics (seismic) and basin dynamics. Some of the more specialized stuff (production geology, sequence stratigraphy) can maybe wait till later.

What I personally look for in an interview candidate is commitment to a career in the industry, some retention of what they learned at university, and the ability to use that knowledge logically to analyze situations and solve problems.
