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

Wells on this lease

2 wells the state's well register assigns to this lease. Every one has a page. Michigan files the dates a well entered and left the unit, and a unit's members include injection, observation and dry holes — a member is not a producer.
