Lease-level volumes as filed with the Kansas Geological Survey. A blank well count is a month the state filed no count for, not a month with no wells.
Wells on this lease
The state’s well register assigns no well to this lease. 23,174 of 98,639 Kansas leases are in that position — a lease is a production unit, and the register does not always name the holes under it.
