Authorized Injection Well — Chautauqua County

278 of the 14,371 wells on the register in Chautauqua County — 1.9% — carry this class.

What this class means

authorised to receive fluid — saltwater disposal or enhanced recovery — not to produce it.

Chautauqua County holds 1.8% of the wells in this class statewide, while holding 2.8% of the register overall — so the class is under-represented here.

What stands out among these

The operator named on most of these records is Kansas Energy Company, L.l.c, on 18 of them (6.5%), ahead of Sm Oil & Gas, INC (14) and Jones Oil Exploration, LLC (8). The oldest well here was completed in 1967 and the most recent in 2026, and the deepest reaches 3652 feet — Fulsom Ranch 2a-7-33-9, drilled in 2013.

An old well on land in Chautauqua County?

0 wells in Chautauqua County were plugged at the State’s expense, out of 278 on the register — the sign that an operator was gone. If you find a well on your land, report it and do not tidy it up: knocking over casing can make you the responsible party. This site reads the register; it does not plug wells. Tell us where and we pass the request to Kansas operators and consultants.

We recommend nobody and we are nobody's agent. We have no arrangement with any firm today — we are collecting these requests in order to go and find them. What we do with this.

The wells

Authorized Injection Well, Chautauqua County — the last column reads yes where the register records the well as plugged, State where it was plugged at public expense, and a dash where neither. A 0 depth means none was reported. The legal description is on the record, never on a page.
