SULLIVAN DEEP "A"

SULLIVAN DEEP "A" is a Texas gas lease in Brooks County, Railroad Commission district 04, operated by Tecpetrol Operating LLC. It has 1 wellbore on file with the Commission. Reported production runs from November 2011 to August 2026, totalling 984,056 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 $365K, with roughly $108K 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 2,562 thousand cubic feet a month. Its strongest month on the record we hold was June 2021, at 16,847 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.
