WHIRLAWAY 100-101 A
WHIRLAWAY 100-101 A is a Texas oil lease in Ward County, Railroad Commission district 08, operated by Manti Tarka Permian Op, LLC. It has 1 wellbore on file with the Commission. Reported production runs from August 2019 to August 2026, totalling 456,444 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 $14.6M, with roughly $3.9M 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 4,807 barrels a month. Its strongest month on the record we hold was January 2022, at 29,448 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.
