Yes, I had the opportunity to sell my tank (pond) water to XTO for hydraulic fracturing a horizontalwell that was situated 300+ feet from my fence line. I said "NO." And that was that!
In Texas, a neighboring well has to be within a "certain" number of feet from the adjoining property line. RRC can tell you how many. BUT, watch out for "exceptions" to the rule that the RRC can grant, but those exceptions require a lengthy hearing process.
Good luck,
Pat
