DORR -A-
DORR -A- is a Texas oil lease in Ward County, Railroad Commission district 08, operated by Olsen Energy Inc. It has 4 wellbores on file with the Commission. Reported production runs from January 1993 to August 2026, totalling 80,793 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 $107K, with roughly $21K 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 16 barrels a month, about 4 per wellbore. Its strongest month on the record we hold was October 2017, at 160 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.
