Lease-level volumes as filed with the Michigan Department of Environment, Great Lakes, and Energy.

Monthly gas sold production

72 months filed with the Michigan Department of Environment, Great Lakes, and Energy, Jan 1997 to Dec 2002. 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.
