HARRISON, W. LEE UNIT
HARRISON, W. LEE UNIT is a Texas oil lease in Lubbock County, Railroad Commission district 8A, operated by Tamarack Petroleum Company, Inc. It has 39 wellbores on file with the Commission. Reported production runs from January 1993 to August 2026, totalling 1,754,516 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 $6.7M, with roughly $1.6M 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 2,217 barrels a month, about 57 per wellbore. Its strongest month on the record we hold was January 2018, at 3,069 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.
