SIBLEY
SIBLEY is a Texas oil lease in Pecos County, Railroad Commission district 08, operated by Warren, Joe H. It has 1 wellbore on file with the Commission. Reported production runs from September 1993 to August 2026, totalling 11,205 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 $2K, with roughly $300 expected over the next twelve months. Over the last twelve months on file it averaged 18 barrels a month. Its strongest month on the record we hold was March 2017, at 35 barrels. In our own backtest, leases producing at this rate are forecast to within about 45% 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.
