It can take quite a long time to get information out of XTO. Did you send your info by certified mail return receipt and include a W-9? That sets a clock to ticking. The well has been online since 2022. Your revenue will be based upon the equation: net acres/actual spacing acres x royalty x percentage of perforations in the section. The percentages are given in your post, so you have part of the info. The decimal from that equation determines how much one received each month. If the acreage was in your wife’s name, you may have a probate to finish before they will give you the proceeds. Contact them again with a certified mail request. Tell them your name, your wife’s name, and demand payment and interest back to first sales. Ask if they are missing anything to clear title. The demand for interest usually helps a bit. Be ready with your address, driver’s license and probate docs, etc.
I do not see a sale for the well, but XTO did sell quite a few wells to Santa Fe recently.
