SPECK
SPECK is a Texas oil lease in Mcculloch County, Railroad Commission district 7C, operated by Geosurveys, Inc. It has 11 wellbores on file with the Commission. Reported production runs from January 1993 to August 2026, totalling 451,341 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 $1.7M, with roughly $394K 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 563 barrels a month, about 51 per wellbore. Its strongest month on the record we hold was June 2023, at 1,017 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.
