Well I downloaded the full list of wells from the Texas Railroad Commission and I go through one by one checking their history on a web portal I have access to. That shows the production history and the well depth etc. I then cross reference back to the RRC if there's one that looks potentially not depleted and check and verify the history of the well. I download logs of data when available and look at the geological properties of the wells if available to see if there are any zones I feel have potential to contain hydrocarbons that they have not accessed. I am ranking everything and then once am done with the full 8000, I will take the higher potential ones, scan through to start doing a deeper dive. The deeper dive involves downloading as much local well information and building up geological models to look for structural geology features that may give a better indication of potential. For that, I use another piece of software that I was the designer for which allows me to build up models of the subsurface and create maps etc.
