BLACK STONE-MARTINADALE A-6
BLACK STONE-MARTINADALE A-6 is a Texas gas lease in Tyler County, Railroad Commission district 06, operated by Anadarko E&P Company LP. It has 1 wellbore on file with the Commission. Reported production runs from March 2006 to August 2026, totalling 3,868,999 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 the whole lease — a 100% undivided interest — at about $2.8M, with roughly $688K 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 2,522 thousand cubic feet a month. Its strongest month on the record we hold was January 2018, at 8,255 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.
