MAR RANCH
MAR RANCH is a Texas oil lease in Atascosa County, Railroad Commission district 01, operated by Atlas Eagle Ford Oper Co, LLC. It has 4 wellbores on file with the Commission. Reported production runs from May 2017 to August 2026, totalling 1,114,937 barrels. 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 $5.6M, with roughly $1.4M 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 2,129 barrels a month, about 532 per wellbore. Its strongest month on the record we hold was June 2017, at 90,215 barrels. 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.
