MCCULLOUGH-WINEMAN EF
MCCULLOUGH-WINEMAN EF is a Texas oil lease in Brazos County, Railroad Commission district 03, operated by Apache Corporation. It has 2 wellbores on file with the Commission. Reported production runs from January 2015 to August 2026, totalling 216,148 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 $1.6M, with roughly $423K 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 493 barrels a month, about 247 per wellbore. Its strongest month on the record we hold was May 2016, at 3,618 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.
