COLUNGA
COLUNGA is a Texas oil lease in Atascosa County, Railroad Commission district 01, operated by W.W.R. Inc. It has 8 wellbores on file with the Commission. Reported production runs from January 1993 to August 2026, totalling 12,701 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 $77K, with roughly $15K 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 36 barrels a month, about 4 per wellbore. Its strongest month on the record we hold was May 2016, at 114 barrels. In our own backtest, leases producing at this rate are forecast to within about 45% 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.
