KM-WINTERBOTHAM UNIT ZAV
KM-WINTERBOTHAM UNIT ZAV is a Texas oil lease in Zavala County, Railroad Commission district 01, operated by Exco Operating Company, LP. It has 1 wellbore on file with the Commission. Reported production runs from August 2018 to August 2026, totalling 517,310 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 $4.2M, with roughly $1.4M 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 2,215 barrels a month. Its strongest month on the record we hold was December 2018, at 27,679 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.
