ARMSTRONG HORIZONTAL UNIT
ARMSTRONG HORIZONTAL UNIT is a Texas oil lease in Mcmullen County, Railroad Commission district 01, operated by Eog Resources, Inc. It has 4 wellbores on file with the Commission. Reported production runs from October 2015 to August 2026, totalling 810,217 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 $25.1M, with roughly $7.6M 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 14,998 barrels a month, about 3,750 per wellbore. Its strongest month on the record we hold was August 2024, at 73,143 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.
