WELCH-COX W39O
WELCH-COX W39O is a Texas oil lease in Martin County, Railroad Commission district 08, operated by Pioneer Natural Res. USA, Inc. It has 1 wellbore on file with the Commission. Reported production runs from August 2022 to August 2026, totalling 252,720 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 $891K 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 2,420 barrels a month. Its strongest month on the record we hold was May 2023, at 19,434 barrels. In our own backtest, leases producing at this rate are forecast to within about 17% 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.
