TONYA
TONYA is a Texas oil lease in Borden County, Railroad Commission district 8A, operated by ST. Mary Land & Exploration Co. It has 3 wellbores on file with the Commission. Reported production runs from November 2008 to August 2026, totalling 431,050 barrels. The lease is currently producing. Fitting a decline curve to that history and pricing the remaining production at today's forward curve values the whole lease — a 100% undivided interest — at about $2.7M, with roughly $672K expected over the next twelve months. An individual royalty owner receives their own decimal interest times that figure. Over the last twelve months on file it averaged 968 barrels a month, about 323 per wellbore. Its strongest month on the record we hold was June 2020, at 2,408 barrels. In our own backtest, leases producing at this rate are forecast to within about 22% of what they went on to produce, and that measured error is the range shown on the page rather than a confidence of our own devising.
