SWILLEY SAND /COCKFIELD/ UNIT
SWILLEY SAND /COCKFIELD/ UNIT is a Texas oil lease in Liberty County, Railroad Commission district 03, operated by Omimex Petroleum, Inc. It has 5 wellbores on file with the Commission. Reported production runs from January 1993 to August 2026, totalling 202,357 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 $565K, with roughly $259K 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 505 barrels a month, about 101 per wellbore. Its strongest month on the record we hold was August 2023, at 1,064 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.
