MILLER UNIT ZAV
MILLER UNIT ZAV is a Texas oil lease in Zavala County, Railroad Commission district 01, operated by Exco Operating Company, LP. It has 2 wellbores on file with the Commission. Reported production runs from January 2018 to August 2026, totalling 660,259 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 $4.5M, with roughly $1.2M 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 2,120 barrels a month, about 1,060 per wellbore. Its strongest month on the record we hold was April 2018, at 23,279 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.
