ROCK HOLLOW
ROCK HOLLOW is a Texas oil lease in Irion County, Railroad Commission district 7C, operated by Fiml Natural Resources, LLC. It has 60 wellbores on file with the Commission. Reported production runs from September 2011 to August 2026, totalling 3,045,831 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 $35.9M, with roughly $8.7M 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 7,433 barrels a month, about 124 per wellbore. Its strongest month on the record we hold was December 2022, at 59,115 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.
