MARY CATHERINE UNIT

MARY CATHERINE UNIT is a Texas oil lease in Robertson County, Railroad Commission district 03, operated by Holley Oil Company, LLC. It has 1 wellbore on file with the Commission. Reported production runs from August 2018 to August 2026, totalling 16,105 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 $275K, with roughly $53K 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 71 barrels a month. Its strongest month on the record we hold was September 2018, at 2,244 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.
