The oil glut in the 1980's and the resulting down turn in the industry lasted at least six years with the price of crude diving 46% in 1986. I've read estimates that the number of jobs lost nation-wide was 450,000. The short version of the cause of the glut was "reduced demand coupled with OPEC's flooding the market with crude in an attempt to re-gain market share."

This could get much worse before it gets better. Buckle up.
For those of you fortunate enough to leave with severance packages and your pensions intact, many of us weren't that lucky back in the '80's. Think Geophysicists working at 7-11. Quit your whining, put your big boy/girl pants on and get on with your life.
