### What happened to these wells — in Montgomery County

**8,225** of the 22,449 wells in Montgomery County are classed as
plugged and abandoned. **1,822** were plugged
**at the State’s expense** because no responsible party
could be found, and **1,157** 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, 6,918 of these wells have a date on file.

### An old well on land in Montgomery County?

1,822 wells in Montgomery County were plugged at the State’s expense, out of 22,449 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](/privacy.md).

### Wells in Montgomery County

*Montgomery 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.*
