The Ray field
317 wells — 0.1% of the Kansas register.

What happened to these wells — in the Ray field
228 of the 317 wells in the Ray field are classed as plugged and abandoned. 0 were plugged at the State’s expense because no responsible party could be found, and 9 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, 199 of these wells have a date on file. What each class means.
Producing formations
| Formation | Wells | Share |
|---|---|---|
| Grnt | 24 | 7.6% |
| Reagan | 21 | 6.6% |
| Arbuckle | 12 | 3.8% |
| Pslv | 5 | 1.6% |
| Reagan Sand | 5 | 1.6% |
| Lansing Kansas City | 3 | 0.9% |
| Regn | 2 | 0.6% |
| Toronto Limestone | 2 | 0.6% |
| Toronto Limestone; Lansing | 2 | 0.6% |
| Grant Shale Member | 2 | 0.6% |
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?
0 wells in Kansas were plugged at the State’s expense, out of 317 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.
