Monthly gas sold production

132 months filed with the Michigan Department of Environment, Great Lakes, and Energy, Jan 1982 to Dec 1992. Volumes are MCF at lease level — a lease can cover many wells, so this is not a well's output. This is gas SOLD, which is what left the unit. Michigan files no produced-gas volume, so the two are not the same number and this page does not present one as the other.
