What happened to these wells — on the St Louis

288 of the 947 wells on the St Louis are classed as plugged and abandoned. 0 were plugged at the State’s expense because no responsible party could be found, and 82 sit on the register as inactive — neither producing nor plugged.

⚠️ Two fields in this register disagree, and we show both rather than pick one: across Kansas, 245,220 wells are classed as plugged but 92,867 of them carry no plugging date, while 26,002 wells carry a date under another class. Here, 288 of these wells have a date on file. What each class means.

An old well on land in Kansas?

0 wells in Kansas were plugged at the State’s expense, out of 947 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

The St Louis formation — 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.
