BILLY 135A
BILLY 135A is a Texas oil lease in Martin County, Railroad Commission district 08, operated by Crownquest Operating, LLC. It has 2 wellbores on file with the Commission. Reported production runs from January 2018 to August 2026, totalling 98,109 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 $654K, with roughly $211K 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 407 barrels a month, about 203 per wellbore. Its strongest month on the record we hold was January 2019, at 3,231 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.
