The Wildcat field
36,703 wells — 7.1% of the Kansas register.
What stands out in the Wildcat field
The operator named on most of these records is Murfin Drilling Co., INC, on 536 of them (1.5%), ahead of Samuel Gary Jr. and Assoc., INC (387) and John O. Farmer, INC (366). The oldest well here was completed in 1900 and the most recent in 2026, and the deepest reaches 11300 feet — Noel Poersch 1, drilled in 1984.

What happened to these wells — in the Wildcat field
28,686 of the 36,703 wells in the Wildcat field are classed as plugged and abandoned. 38 were plugged at the State’s expense because no responsible party could be found, and 297 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, 20,140 of these wells have a date on file. What each class means.

The formation is recorded on only 21 % of Kansas wells, so this table describes the minority that carry one.

An old well on land in Kansas?
38 wells in Kansas were plugged at the State’s expense, out of 36,703 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.
