Well, I just checked the Chevron website to see what is happening with employment openings. All of these stupid news reports about the big upswing in oil industry hiring does not feel quite right. Probably 95% or more are for field workers, not professionals.
Here is what I found for Chevron for all worldwide vacancies. Earth Science - zero, Drilling and Completions - zero, Petroleum Engineering - zero, Facilities Engineering - 3 ( 1 in El Segundo, 2 in Thailand). Not much, but remember, this is Chevron.
Home of bloat, endless meetings, diversity and s-xual orientation quotas, friends and family protected employees, etc. This company is not exactly friendly to actual earth science professionals and engineers who actually do the work to find and produce oil and natural gas.
