You seem to be quite a good candidate. Have a great GMAT, are in a great industry (although I would hold off on final judgement till I hear more about what exactly you did at work, and your promotions, etc.). Whoever told you GPA doesn't matter for internationals is speaking total nonsense. It matters for all.
I think your school list is fantastic (meaning well-chosen) as well as reasonable. You may also want to look at Rice, which for energy people is one of the strongest schools out there (even if it's general ranking is not as high as some other places). You might also think of Tepper which is a very strong feeder school for industry, or Ross because of its regional proximity to the "Fracking boom" (and of course both are excellent schools).
Things look pretty good from here. If you would like a more detailed evaluation, I'd invite you to send over your info: http://admissionado.com/mba/free-consultation/
