SENTINEL STATE 55-28 UNIT
SENTINEL STATE 55-28 UNIT is a Texas gas lease in Reeves County, Railroad Commission district 08, operated by Cimarex Energy Co. It has 1 wellbore on file with the Commission. Reported production runs from May 2019 to August 2026, totalling 2,513,674 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 $4.2M, with roughly $1.5M 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 14,858 thousand cubic feet a month. Its strongest month on the record we hold was July 2019, at 124,047 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.
