PORTERFIELD-GIFFORD HILL UNIT
PORTERFIELD-GIFFORD HILL UNIT is a Texas oil lease in Brazos County, Railroad Commission district 03, operated by Union Pacific Resources Company. It has 2 wellbores on file with the Commission. Reported production runs from November 1993 to August 2026, totalling 377,662 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 $907K, with roughly $173K 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 186 barrels a month, about 93 per wellbore. Its strongest month on the record we hold was September 2025, at 449 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.
