Where does an education woman go to find work overseas?

On vacation last week I met a person that works for an oil company based out of Texas. He said he used to be a psychologist but found this work to be more rewarding and he makes much more money working out of the country. He said I should try it too. I have taught school 12 years, I have a master's degree and I am so burned out I quit teaching. I can't find where these companies are. They are exploration (drilling) oil companies. Can anyone offer advise for this or anything interesting like this? I might should mention I am a woman and I am willing to work in harsh environments to retire early.
