SINCLAIR 8A
SINCLAIR 8A is a Texas oil lease in Reagan County, Railroad Commission district 7C, operated by Bold Operating, LLC. It has 1 wellbore on file with the Commission. Reported production runs from August 2016 to August 2026, totalling 326,235 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 $3.3M, with roughly $794K 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 753 barrels a month. Its strongest month on the record we hold was May 2017, at 24,138 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.
