WELDER, E.H. -C-
WELDER, E.H. -C- is a Texas oil lease in San Patricio County, Railroad Commission district 04, operated by Marathon Oil Company. It has 1 wellbore on file with the Commission. Reported production runs from January 1996 to August 2026, totalling 63,526 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 $1.6M, with roughly $351K 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 501 barrels a month. Its strongest month on the record we hold was April 2025, at 565 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.
