LLM ZAV
LLM ZAV is a Texas oil lease in Zavala County, Railroad Commission district 01, operated by Chesapeake Operating, Inc. It has 5 wellbores on file with the Commission. Reported production runs from September 2011 to August 2026, totalling 403,993 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 $3.1M, with roughly $779K 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 1,000 barrels a month, about 200 per wellbore. Its strongest month on the record we hold was June 2018, at 3,484 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.
