TENAMPA
TENAMPA is a Texas oil lease in Bexar County, Railroad Commission district 01, operated by Drachen Oil Company. It has 10 wellbores on file with the Commission. Reported production runs from June 2005 to August 2026, totalling 8,390 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 $63K, with roughly $12K 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 16 barrels a month, about 2 per wellbore. Its strongest month on the record we hold was August 2022, at 125 barrels. In our own backtest, leases producing at this rate are forecast to within about 45% 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.
