MANSFIELD
MANSFIELD is a Texas oil lease in Wise County, Railroad Commission district 09, operated by Gonzenbach, Glen D. It has 2 wellbores on file with the Commission. Reported production runs from June 1996 to August 2026, totalling 24,143 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 $408K, with roughly $65K 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 54 barrels a month, about 27 per wellbore. Its strongest month on the record we hold was November 2021, at 88 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.
