What happened to these wells — on the Morrow
898 of the 1,978 wells on the Morrow are classed as plugged and abandoned. 2 were plugged at the State’s expense because no responsible party could be found, and 150 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, 885 of these wells have a date on file. What each class means.
An old well on land in Kansas?
2 wells in Kansas were plugged at the State’s expense, out of 1,978 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.
