Disclaimer: there may be errors. I did this quickly and did not double-check. The numbers will not add up to the total number of wells on the confidential list because the confidential list includes a few salt water disposal wells which I do not track. On the other hand, some salt water disposal wells have slipped into the numbers above; for example I see there are a couple of salt water disposal wells among the CLR wells that are on the confidential list.
