UNIVERSITY 18-58
UNIVERSITY 18-58 is a Texas oil lease in Reagan County, Railroad Commission district 7C, operated by Callon Petroleum Operating Co. It has 2 wellbores on file with the Commission. Reported production runs from November 2013 to August 2026, totalling 81,272 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 $1.3M, with roughly $282K 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 400 barrels a month, about 200 per wellbore. Its strongest month on the record we hold was August 2021, at 3,315 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.
