TMK UNIT C
TMK UNIT C is a Texas oil lease in Karnes County, Railroad Commission district 02, operated by Gulftex Energy, LLC. It has 1 wellbore on file with the Commission. Reported production runs from December 2021 to August 2026, totalling 246,760 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 $1.8M, with roughly $793K 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 1,417 barrels a month. Its strongest month on the record we hold was December 2021, at 32,031 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.
