Here, 452 of these wells have a date on file. [What each class means](/orphaned.md). ### An old well on land in Kansas? 4 wells in Kansas were plugged at the State’s expense, out of 1,051 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). ### The wells *The Viola formation — 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.* | Lease and well | Operator | Field | Depth (ft) | Year | Plugged | |---|---|---|---|---|---| | [Thomsen 1-hp](/search.md) API 15-031-22572 | Haas Petroleum, LLC | Pieratt | 1455 | 2010 | State | | [Mcmillan 4](/search.md) API 15-185-23250 | Key Gas Corp | Mcmillan | 3652 | 2004 | State | | [Fischer 1](/search.md) API 15-185-21715 | Panther Energy Corp | Drach South | 3842 | 1983 | State | | [Hoffman Trust 2](/search.md) API 15-033-21251 | Western Plains | Wildcat | 496 | — | State | | [Beadles Tatum 4](/search.md) API 15-015-24235 | Brickley Enterprises, LLC | — | 3167 | 2025 | — | | [Seglem 4](/search.md) API 15-015-24240 | Darrah Oil Company, LLC | Reynolds-schaffer | 3120 | 2025 | — | | [W&g Owwo 1](/search.md) API 15-017-20920-0001 | Darrah Oil Company, LLC | Koegeboehn | 2488 | 2025 | — | | [Ils Land LLC 1](/search.md) API 15-145-21904 | Jel Resources, LLC | Benson | 4079 | 2025 | — | | [Marguerite #1](/search.md) API 15-151-22612 | Griffin, Charles N | Earl | 4773 | 2025 | — | | [Kay's 1-7](/search.md) API 15-185-24174 | Rama Operating Co., INC | Newell | 4000 | 2025 | — | | [Wiw 4](/search.md) API 15-095-22362 | Northern Natural Gas CO | — | 4323 | 2025 | — | | [Alley 16-43 Ob](/search.md) API 15-095-22363 | Northern Natural Gas CO | — | 4505 | 2025 | — | | [Mayce 1](/search.md) API 15-007-24512 | Griffin, Charles N | Turkey Creek East | 4897 | 2025 | — | | [Jenna 1](/search.md) API 15-007-24513 | Griffin, Charles N | Turkey Creek East | 4864 | 2025 | — | | [Wright 3](/search.md) API 15-015-24216 | Jordan Oil Management INC | Whitewater | 2623 | 2024 | — | | [Griffith 21](/search.md) API 15-151-22588 | Thomas Garner, INC | Rose Valley South | 4495 | 2024 | — | | [Ramondetta 3](/search.md) API 15-015-24224 | Vess Oil Corporation | El Dorado | 2620 | 2024 | — | | [Ramondetta 5](/search.md) API 15-015-24225 | Vess Oil Corporation | Hopkins Switch | 3129 | 2024 | — | | [Tanner 3](/search.md) API 15-185-24151 | Lachenmayr Oil LLC | — | 4350 | 2024 | — | | [Peterson Trust 8-31](/search.md) API 15-111-20567 | Mull Drilling Company, INC | — | 3198 | 2024 | — | | [Peterson Trust 9-31](/search.md) API 15-111-20568 | Mull Drilling Company, INC | — | 3200 | 2024 | — | | [Peterson Trust 11-31](/search.md) API 15-111-20569 | Mull Drilling Company, INC | — | 3451 | 2024 | — | | [Peterson Trust 10-31](/search.md) API 15-111-20570 | Mull Drilling Company, INC | — | 3201 | 2024 | — | | [Ethan 2](/search.md) API 15-007-24498 | Griffin, Charles N | Turkey Creek East | 4868 | 2024 | — | | [Dunkle 7](/search.md) API 15-015-24232 | White & Ellis Drilling, INC | El Dorado | 2836 | 2024 | — | | [Willbanks 1-9](/search.md) API 15-033-21800 | Thoroughbred Associates L.l.c | Unnamed | 5960 | 2024 | — | | [Madelyn 2](/search.md) API 15-007-21982-0001 | Griffin, Charles N | Turkey Creek East | 4876 | 2024 | — | | [Madelyn 1](/search.md) API 15-007-24499 | Griffin, Charles N | Turkey Creek East | 4867 | 2024 | — | | [Peterson Trust 4-31](/search.md) API 15-111-20561 | Mull Drilling Company, INC | — | 3300 | 2023 | — | | [Peterson Trust 3-31](/search.md) API 15-111-20562 | Mull Drilling Company, INC | Rainbow Ridge Northwest | 3250 | 2023 | — | | [Bushwood 1-26](/search.md) API 15-185-24123 | Edison Operating Company LLC | St. John | 4200 | 2023 | — | | [India 1](/search.md) API 15-185-24126 | Nec Operating -
