MAREK UNIT
MAREK UNIT is a Texas oil lease in Karnes County, Railroad Commission district 02, operated by Eog Resources, Inc. It has 11 wellbores on file with the Commission. Reported production runs from December 2011 to August 2026, totalling 3,842,217 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 $19.4M, with roughly $4.3M 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 5,637 barrels a month, about 512 per wellbore. Its strongest month on the record we hold was April 2018, at 129,575 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.
