Looking for oil field work in OK or TX

I already have a tanker endorsement, and on May15th I submitted digital fingerprints to the TSA, and next Tuesday I will take the Hazmat test. I have no felonies on my record, so I expect to get approval by the TSA within a few weeks. I have taken the Hazmat test several times in years past, and I have passed the test the first time every time. I let my last Hazmat endorsement expire because my employer then didn't require it, and because I would have had to drive quite a ways to get to a testing site.
I do not have experience in pulling tankers, but I have in the past pulled vans with large square containers roughly 4' x 4' x 4' filled with paint, therefore I have pulled sloshing loads around. I fully expect to feel stronger sloshes from baffled tankers. Perhaps I could start out hauling water and migrate to hauling crude when the TSA clears me? I also have worked for over 2 decades as a mechanic albeit not recently, so perhaps that is another option. I have a bit of a million miles of OTR experience plus several years of 10 wheel dump truck driving for an excavating company. I live in Missouri, but I intend to travel to an oilfield next week. I would like to be able to get home every once in awhile. Perhaps working 3 weeks on and getting one off might work? This is negotiable.
I quit my last OTR trucking job a little over a year ago because I was hoping to become self-employed locally. Unfortunately, things haven't worked out well at all. I left the last job on good terms with a great OTR trucking company (FCC), and the owner sent me a "you are welcome to return" letter that I can provide a copy of. I might take him up on that but I would rather earn more money and to try something new. I always got my bonus for driving more than 10,000 miles per month, so I am not afraind of working long hours, but I will not risk my life by driving sleepy. I view the 10 hours off as being minimal, but working 12 hours isn't a problem. I also want consistant times. I prefer to work days, but working nights for awhile until a day position opens up is fine. I will need a place to live at with Internet. I might very well rent an apartment, but I do factor in expenses vs income when I make decissions. Living in a sleeper is an option if I can park somewhere to shower and eat real food as opposed to sandwhiches/ fast food. If I end up living in a man camp then I do not want to live with a smoker or in an area with fights. I'm a peaceful and highly rational person and I do not want to live with or work for grouches and/or backstabbers.
Questions are welcome.

 

Update to my previous post: I have passed the HazMat test and I have also added and passed the doubles test to my tanker endorsement on my CDL. I'm just waiting for the TSA paperwork.
