Due Diligence List

I am about to purchase a working interest in an oil and gas well in Denton County. Although the purchase is small and with a life-long friend I would still like to do my homework. I have some experience but am looking for a checklist of DD items I should have or go through before I finalize my purchase. Any ideas ?
