AZRedhawk44,
You will need a BS in Geology or Engineering (specifically, Petroleum Engineering). This will take 4 years as a full time student, but by then the price of oil will be back up there and the petroleum industry will be hiring like crazy.
I can say from experience that the engineering curriculum is a rough one and requires a strong aptitude for science and math. I can't say anything about geology except that paleontology was the most boring class I ever took in my entire life. The field trips were fun though.
Or consider a degree in renewable energy. An equally hot field these days.
Whatever you decide, good luck.
