CHALK, OTIS
CHALK, OTIS is a Texas oil lease in Howard County, Railroad Commission district 08, operated by Apache Corporation. It has 23 wellbores on file with the Commission. Reported production runs from December 2011 to August 2026, totalling 297,976 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 $1.9M, with roughly $423K 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 642 barrels a month, about 28 per wellbore. Its strongest month on the record we hold was January 2017, at 2,534 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.
