MCCLOSKEY '42B'
MCCLOSKEY '42B' is a Texas oil lease in Martin County, Railroad Commission district 08, operated by Pioneer Natural Res. USA, Inc. It has 2 wellbores on file with the Commission. Reported production runs from April 2013 to August 2026, totalling 101,198 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 $745K, with roughly $169K 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 251 barrels a month, about 126 per wellbore. Its strongest month on the record we hold was October 2018, at 1,065 barrels. In our own backtest, leases producing at this rate are forecast to within about 22% 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.
