MURPHY-SINCLAIR UNIT

MURPHY-SINCLAIR UNIT is a Texas gas lease in Karnes County, Railroad Commission district 02, operated by Marathon Oil Ef LLC. It has 1 wellbore on file with the Commission. Reported production runs from February 2015 to August 2026, totalling 1,394,219 thousand cubic feet. The lease is currently producing. Fitting a decline curve to that history and pricing the remaining production at today's forward curve values a standard royalty share at about $49K, with roughly $13K expected over the next twelve months. Over the last twelve months on file it averaged 2,932 thousand cubic feet a month. Its strongest month on the record we hold was May 2022, at 26,397 thousand cubic feet. 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.
