ERWIN -C-
ERWIN -C- is a Texas oil lease in Midland County, Railroad Commission district 08, operated by Parker & Parsley Development Co. It has 6 wellbores on file with the Commission. Reported production runs from January 1993 to August 2026, totalling 249,489 barrels. The lease is intermittent. 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 $4K, with roughly $659 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 37 barrels a month, about 6 per wellbore. Its strongest month on the record we hold was February 2020, at 3,276 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.
