TURK-WILLIAMS UNIT
TURK-WILLIAMS UNIT is a Texas oil lease in Gonzales County, Railroad Commission district 01, operated by Marathon Oil Ef LLC. It has 2 wellbores on file with the Commission. Reported production runs from May 2012 to August 2026, totalling 326,443 barrels. The lease is intermittent. 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 $8K, with roughly $1K 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 barrels a month. Its strongest month on the record we hold was November 2020, at 4,043 barrels. In our own backtest, leases producing at this rate are forecast to within about 100% 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.
