RATLIFF JGA4
RATLIFF JGA4 is a Texas oil lease in Ector County, Railroad Commission district 08, operated by Cog Operating LLC. It has 1 wellbore on file with the Commission. Reported production runs from December 2025 to August 2026, totalling 138,069 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 $83.3M, with roughly $18.2M 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 24,010 barrels a month. Its strongest month on the record we hold was January 2026, at 30,758 barrels. In our own backtest, leases producing at this rate are forecast to within about 18% 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.
