# The Chase Group formation in Kansas — 8,994 wells > 8,994 Kansas wells produce from the Chase Group formation, at a median depth of 2778 feet. ## The Chase Group formation **8,994** wells name this formation. The field is recorded on only 21 % of the register, so this is the minority that carries one. *Depth, over the 8,986 wells on this formation where a figure was reported (100%) — a median, never a mean* | Measurement | Median | 90th percentile | Kansas median | |---|---|---|---| | Total depth | **2778 ft** | 3067 ft | 2831 ft — shallower here | ### What stands out on the Chase Group The operator named on most of these records is **Amoco Production CO**, on 731 of them (8.1%), ahead of Stanolind Oil and Gas CO (450) and Oxy Usa, INC (357). The oldest well here was completed in **1920** and the most recent in 2024, and the deepest reaches **7745 feet** — Chaffin Unit 'c' 1-4, drilled in 1988. ### Where it is produced | County | Wells | Share | |---|---|---| | [Stevens](/county/stevens.md) | 1,606 | 17.9% | | [Grant](/county/grant.md) | 1,288 | 14.3% | | [Kearny](/county/kearny.md) | 1,257 | 14.0% | | [Finney](/county/finney.md) | 1,254 | 13.9% | | [Haskell](/county/haskell.md) | 860 | 9.6% | | [Seward](/county/seward.md) | 737 | 8.2% | | [Morton](/county/morton.md) | 650 | 7.2% | | [Stanton](/county/stanton.md) | 508 | 5.6% | | [Hamilton](/county/hamilton.md) | 467 | 5.2% | | [Greeley](/county/greeley.md) | 238 | 2.6% | | [Scott](/county/scott.md) | 57 | 0.6% | | [Pawnee](/county/pawnee.md) | 17 | 0.2% | | Wichita | 15 | 0.2% | | [Gray](/county/gray.md) | 4 | 0.0% | | [Barton](/county/barton.md) | 3 | 0.0% | | [Hodgeman](/county/hodgeman.md) | 2 | 0.0% | | [Barber](/county/barber.md) | 1 | 0.0% | | [Kingman](/county/kingman.md) | 1 | 0.0% | | [Meade](/county/meade.md) | 1 | 0.0% | | [Reno](/county/reno.md) | 1 | 0.0% | ### In which fields | Field | Wells | Share | |---|---|---| | [Hugoton Gas Area](/field/hugoton-gas-area.md) | 7,708 | 85.7% | | [Bradshaw Gas Area](/field/bradshaw-gas-area.md) | 476 | 5.3% | | [Hugoton](/field/hugoton.md) | 268 | 3.0% | | [Panoma Gas Area](/field/panoma-gas-area.md) | 176 | 2.0% | | Byerly | 71 | 0.8% | | [Unknown](/field/unknown.md) | 36 | 0.4% | | Hugoton Northeast Gas Area | 32 | 0.4% | | [Wildcat](/field/wildcat.md) | 13 | 0.1% | | [Kismet](/field/kismet.md) | 12 | 0.1% | | Bradshaw | 12 | 0.1% | | Leoti Gas Area | 11 | 0.1% | | Hugoton North | 8 | 0.1% | | Shuck | 8 | 0.1% | | [Damme](/field/damme.md) | 5 | 0.1% | ### What happened to these wells — on the Chase Group **1,761** of the 8,994 wells on the Chase Group are classed as plugged and abandoned. **22** were plugged **at the State’s expense** because no responsible party could be found, and **379** 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, 1,561 of these wells have a date on file. [What each class means](/orphaned.md). ### An old well on land in Kansas? 22 wells in Kansas were plugged at the State’s expense, out of 8,994 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 Chase Group 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 | |---|---|---|---|---|---| | [H.
