CHALK, MARY
CHALK, MARY is a Texas oil lease in Howard County, Railroad Commission district 08, operated by Legacy Reserves Operating LP. It has 10 wellbores on file with the Commission. Reported production runs from December 2011 to August 2026, totalling 61,624 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 $1.0M, with roughly $235K 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 371 barrels a month, about 37 per wellbore. Its strongest month on the record we hold was April 2025, at 682 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.
