MARTINDALE JARRATT UNIT

MARTINDALE JARRATT UNIT is a Texas oil lease in La Salle County, Railroad Commission district 01, operated by Eog Resources, Inc. It has 2 wellbores on file with the Commission. Reported production runs from March 2013 to August 2026, totalling 379,612 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 $74K, with roughly $27K expected over the next twelve months. Over the last twelve months on file it averaged 1,321 barrels a month, about 660 per wellbore. Its strongest month on the record we hold was December 2025, at 3,103 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.
