If Antero believes you are an heir you should seek to establish that fact. If you do not, funds may accrue to the Mineral Owners Escrow Account in your mothers name (or maybe already have - bonus if the interest was force pooled or perhaps royalties) The MOEA can be checked on the Oklahoma Corporation Commission website. A fraction of an acre could yield some nice spending money.
I believe the following information is your well. The completion report for this well shows an IP -initial production - of a little over 6.5 million cubic feet per day. Date of first sales is 5/14/2011. The link to the completion report is http://imaging.occeweb.com/OG/Well%20Records/1DD01A6D.pdf
