ERLKING UNIT B 21-09
ERLKING UNIT B 21-09 is a Texas oil lease in Borden County, Railroad Commission district 08, operated by Surge Operating, LLC. It has 3 wellbores on file with the Commission. Reported production runs from April 2022 to August 2026, totalling 745,835 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 $22.2M, with roughly $5.7M 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 8,788 barrels a month, about 2,929 per wellbore. Its strongest month on the record we hold was June 2022, at 35,790 barrels. In our own backtest, leases producing at this rate are forecast to within about 17% 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.
