DCR 257
DCR 257 is a Texas oil lease in Duval County, Railroad Commission district 04, operated by Sonat Exploration Co. - Houston. It has 2 wellbores on file with the Commission. Reported production runs from March 1994 to August 2026, totalling 59,530 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 $121K, with roughly $23K 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 33 barrels a month, about 17 per wellbore. Its strongest month on the record we hold was January 2020, at 111 barrels. In our own backtest, leases producing at this rate are forecast to within about 45% 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.
