posted a few thing in the past on this. Orphaned wells are abandoned oil wells. They're not great for the environment and states try to get them abandoned correctly. There are lists. I am looking through a list of over 8000 from Texas and diving into the geology a little to see if I can find ones that could potentially be economic and be put back on production. Been going a couple months now. Rather large project! Trying to see if one can start an oil company with very little capital just for a good challenge.
