UTL 4231A
UTL 4231A is a Texas oil lease in Winkler County, Railroad Commission district 08, operated by Continental Resources, Inc. It has 1 wellbore on file with the Commission. Reported production runs from June 2025 to August 2026, totalling 157,635 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 $34.2M, with roughly $7.6M 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 13,633 barrels a month. Its strongest month on the record we hold was July 2025, at 31,152 barrels. In our own backtest, leases producing at this rate are forecast to within about 18% 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.
