Monthly oil production

Monthly gas sold production
18 months filed with the Michigan Department of Environment, Great Lakes, and Energy, Jan 1982 to Jan 1984. 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.
