NELLIST-SCHWALM
Lease 5520 · ROSCOMMON County, Michigan · Saint Helen field · Det. River Richfield
Monthly gas sold production
57 months filed with the Michigan Department of Environment, Great Lakes, and Energy, Jan 1988 to Oct 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.
The Michigan Department of Environment, Great Lakes, and Energy records first production from this unit in 1958, and the monthly series below begins in Jan 1988. The total above covers the months shown, not the life of the unit.
