OLSEN
OLSEN is a Texas oil lease in Nueces County, Railroad Commission district 04, operated by Tag Operating Company, Inc. It has 1 wellbore on file with the Commission. Reported production runs from January 2021 to August 2026, totalling 38,990 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 $758K, with roughly $146K 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 210 barrels a month. Its strongest month on the record we hold was January 2021, at 2,462 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.
