SHACKELFORD 10-39I
SHACKELFORD 10-39I is a Texas oil lease in Midland 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 May 2025 to August 2026, totalling 181,307 barrels. The lease is intermittent. 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 $18.9M, with roughly $12.3M 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 13,579 barrels a month. Its strongest month on the record we hold was December 2025, at 42,649 barrels. In our own backtest, leases producing at this rate are forecast to within about 18% 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.
