STS SOUTH DW
STS SOUTH DW is a Texas gas lease in Mcmullen County, Railroad Commission district 01, operated by Caturus Energy, LLC. It has 1 wellbore on file with the Commission. Reported production runs from July 2025 to August 2026, totalling 1,604,737 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 $18.2M, with roughly $3.2M 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 151,914 thousand cubic feet a month. Its strongest month on the record we hold was August 2025, at 279,861 thousand cubic feet. In our own backtest, leases producing at this rate are forecast to within about 18% 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.
