ROBERT WALKER UNIT ZAV B
ROBERT WALKER UNIT ZAV B is a Texas oil lease in Zavala County, Railroad Commission district 01, operated by Exco Operating Company, LP. It has 3 wellbores on file with the Commission. Reported production runs from July 2014 to August 2026, totalling 1,000,677 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 $13.2M, with roughly $3.0M 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 4,123 barrels a month, about 1,374 per wellbore. Its strongest month on the record we hold was September 2019, at 53,697 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.
