The Kraft-prusa field
2,239 wells — 0.4% of the Kansas register.
What stands out in the Kraft-prusa field
The operator named on most of these records is Black Marshall Oil CO, on 86 of them (3.8%), ahead of Gulf Oil Corp (68) and Skelly Oil CO (52). The oldest well here was completed in 1930 and the most recent in 2026, and the deepest reaches 3985 feet — Prusa 1, drilled in 1948.
| Measurement | Median | 90th percentile | Kansas median |
|---|---|---|---|
| Total depth | 3350 ft | 3426 ft | 2831 ft — deeper here |
What happened to these wells — in the Kraft-prusa field
1,540 of the 2,239 wells in the Kraft-prusa field are classed as plugged and abandoned. 5 were plugged at the State’s expense because no responsible party could be found, and 28 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, 823 of these wells have a date on file. What each class means.
Producing formations
| Formation | Wells | Share |
|---|---|---|
| Arbuckle | 153 | 6.8% |
| Arbuckle, Lansing Kansas City | 12 | 0.5% |
| Arbuckle Group | 8 | 0.4% |
| Lansing-kansas City | 7 | 0.3% |
| Lansing | 3 | 0.1% |
| Lansing Kansas City | 2 | 0.1% |
| Mississippi | 2 | 0.1% |
| Lansing-kansas City, Penn Basal Cong | 1 | 0.0% |
| Pennsylvania Conglomerate | 1 | 0.0% |
| Cgmplv | 1 | 0.0% |
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?
5 wells in Kansas were plugged at the State’s expense, out of 2,239 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.
