Hey thanks, I had never thought of doing it that way (through the back door so to speak). That sure will give me a figure close enough to decide what needs to happen next. I am cautious because I do know at one time back in 1970 or so the wells had all but stopped producing.
Thanks again, that sure solves one of my roadblocks in fine shape! Now on with finding the mineral rights he had that I have not yet discovered, there may be some or none.
