COLONIAL UNIT A1
COLONIAL UNIT A1 is a Texas oil lease in Howard County, Railroad Commission district 08, operated by Callon Petroleum Operating Co. It has 1 wellbore on file with the Commission. Reported production runs from May 2017 to August 2026, totalling 377,027 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 $4.6M, with roughly $1.1M 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 1,440 barrels a month. Its strongest month on the record we hold was August 2017, at 24,695 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.
