COCKBURN, H. C.
COCKBURN, H. C. is a Texas oil lease in Wharton County, Railroad Commission district 03, operated by Exxon Corp. It has 143 wellbores on file with the Commission. Reported production runs from January 1993 to August 2026, totalling 6,550,029 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 $22.0M, with roughly $5.0M 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 7,604 barrels a month, about 53 per wellbore. Its strongest month on the record we hold was May 2016, at 25,548 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.
