Sounds like you've been through a lot off the field. Hang in there.
However... let me clue you in about something I've been associated with all of my life - The Oil Business.
Oil is a commodity business. All that matters is the price of a barrel of oil. It doesn't matter if its from Russia, Saudi Arabia, Venezuela or Alaska or wherever.
When the price of oil is high - i.e. $100/bbl, the industry booms and there are plenty of jobs.
When the price of oil is low - i.e. under $30/bbl. the industry grinds to a halt and it's very difficult for anybody to find work. Everybody gets laid off.
Oil comes out of the ground or the ocean floor wherever they find it. And that "wherever" ain't The Woodlands.
One of the most important things my father ever told me is "ya gotta go where the work is". In his case, that was Puerto Rico, Alaska, Saudia Arabia 2x, Indonesia, etc.
One of my best friends is a PETE grad from the mid-1990s and he's enjoyed a great run but the past two years have been a rough time for him.
I'm also close to a recent PETE grad who graduated at the top of his class and got a job working offshore in a part of the world that I have no desire to travel to (see earlier advice from my dad). I think a lot of PETE grads from the past 5-10 years assumed that they'd all have cushy office jobs in Houston making beaucoups dollars. The reality is when that commodity price bottoms out, jobs dry up. When it tops out - which might never happen again, jobs will be plentiful.
And with respect to the Aggie Network working/not-working, this thread/post is an example of the Aggie Network working for you.
From 1974 to 1986, my family enjoyed a wild ride on the back of the price of a barrel of oil. Your time will come. But... "Ya gotta go where the work is" when that time comes. And that might be Southeast Asia, it might be offshore in the Gulf of Mexico or the North Sea or it could even be in Africa.
