I'll reinforce "Nearly Retired's" enthusiasm for the Gulf O'Mexico flying- a quarter century ago.
But- I spent almost all my 13, 14 years on offshore jobs and was very fortunate in being assigned a relatively 'cush' job at a little better than two years in. I was my own boss within company and contract terms. I flew Twinstars (I hated Twinstars eventually, the only reason I bid up to IFR) for a pipeline company, they worked 0700 to 1900 when the days were that long and whatever daylight available after 0700 when the days were shorter.
Good accomodations, mostly good crew, only a couple psychopaths (one field boss), treated me well overall.
It was only a 4 or 5 day a shift contract, so I was a pool pilot for 2 or 3 days, so I had variety in jobs and some in airframes- I've flown straight 355Fs, F1s and F2s and all the 206s but no 407 time, often going back and forth in airframes on the same day.
I intensely disliked beach bases and company politics. One was at the whim of whoever was running the base that day, the lead pilot, base/area manager or whoever was on the dispatch desk.
The training provided by the training department was the best I ever had- instructors were required to fly the line, and took respected line pilot input. Most of the company instructional staff went on to be management in the company and others.
As to the 'critters'- I am biased, I liked Cajuns, hung out with them. I get along everywhere I go, I like beer joints, whatever is on offer, wherever I am- I just want to pass a good time, me, yeah. The crews were generally a lot more educated and entrepreneurial than obvious at a casual glance. That's 'company' crew, the contract hands were a much more diverse bunch and might well be highs school dropouts or whatever. Talk to'em and you might discover that D&C (Danos and Curole, the major labor contractor where and when) hand was educated, ambitious and working towards a Chevron, whatever job- much better money and bennies, long term security and a week, two weeks on and off.
Life, the job is what you make it. You can be as miserable or as happy as you want, just be willing to do the job and/or shine it on when you get tired of it. I still hate Twinstars.
