STUMBERG RANCH UNIT D

STUMBERG RANCH UNIT D is a Texas oil lease in Dimmit County, Railroad Commission district 01, operated by SN Ef Maverick, LLC. It has 8 wellbores on file with the Commission. Reported production runs from February 2019 to August 2026, totalling 780,288 barrels. The lease is currently producing. Fitting a decline curve to that history and pricing the remaining production at today's forward curve values a standard royalty share at about $103K, with roughly $32K expected over the next twelve months. Over the last twelve months on file it averaged 1,818 barrels a month, about 227 per wellbore. Its strongest month on the record we hold was April 2019, at 73,975 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.

Production figures are as reported to the Railroad Commission of Texas. The value shown is an estimate produced by fitting a decline curve to that reported history; it is not an offer or an appraisal.
