# The Bartlesville formation in Kansas — 10,057 wells > 10,057 Kansas wells produce from the Bartlesville formation, at a median depth of 871 feet. ## The Bartlesville formation **10,057** 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 7,624 wells on this formation where a figure was reported (76%) — a median, never a mean* | Measurement | Median | 90th percentile | Kansas median | |---|---|---|---| | Total depth | **871 ft** | 1150 ft | 2831 ft — shallower here | ### What stands out on the Bartlesville The operator named on most of these records is **Colt Energy INC**, on 579 of them (5.8%), ahead of Running Foxes Petroleum INC (572) and Tailwater, INC (351). The oldest well here was completed in **1938** and the most recent in 2026, and the deepest reaches **9326 feet** — Thomas B 12, drilled in 2013. ### Where it is produced | County | Wells | Share | |---|---|---| | [Johnson](/county/johnson.md) | 2,022 | 20.1% | | [Allen](/county/allen.md) | 1,914 | 19.0% | | [Bourbon](/county/bourbon.md) | 1,298 | 12.9% | | [Crawford](/county/crawford.md) | 654 | 6.5% | | [Wilson](/county/wilson.md) | 645 | 6.4% | | [Linn](/county/linn.md) | 611 | 6.1% | | [Anderson](/county/anderson.md) | 604 | 6.0% | | [Labette](/county/labette.md) | 496 | 4.9% | | [Woodson](/county/woodson.md) | 343 | 3.4% | | [Franklin](/county/franklin.md) | 331 | 3.3% | | [Miami](/county/miami.md) | 209 | 2.1% | | [Douglas](/county/douglas.md) | 186 | 1.8% | | [Montgomery](/county/montgomery.md) | 186 | 1.8% | | [Greenwood](/county/greenwood.md) | 179 | 1.8% | | [Neosho](/county/neosho.md) | 177 | 1.8% | | Cherokee | 47 | 0.5% | | [Cowley](/county/cowley.md) | 37 | 0.4% | | [Butler](/county/butler.md) | 30 | 0.3% | | [Coffey](/county/coffey.md) | 15 | 0.1% | | [Sumner](/county/sumner.md) | 11 | 0.1% | ### In which fields | Field | Wells | Share | |---|---|---| | [Unknown](/field/unknown.md) | 998 | 9.9% | | [Humboldt-chanute](/field/humboldt-chanute.md) | 623 | 6.2% | | [Iola](/field/iola.md) | 580 | 5.8% | | [Gardner](/field/gardner.md) | 460 | 4.6% | | [Paola-rantoul](/field/paola-rantoul.md) | 351 | 3.5% | | [Bronson-xenia](/field/bronson-xenia.md) | 332 | 3.3% | | [Garnett Shoestring](/field/garnett-shoestring.md) | 287 | 2.9% | | [Walnut Southeast](/field/walnut-southeast.md) | 287 | 2.9% | | [Moran](/field/moran.md) | 259 | 2.6% | | [Blue Mound](/field/blue-mound.md) | 257 | 2.6% | | [Wildcat](/field/wildcat.md) | 247 | 2.5% | | [Neodesha](/field/neodesha.md) | 246 | 2.4% | | [Davis-bronson](/field/davis-bronson.md) | 241 | 2.4% | | Gardner South | 219 | 2.2% | ### What happened to these wells — on the Bartlesville **1,944** of the 10,057 wells on the Bartlesville are classed as plugged and abandoned. **23** were plugged **at the State’s expense** because no responsible party could be found, and **365** 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, 1,985 of these wells have a date on file. [What each class means](/orphaned.md). ### An old well on land in Kansas? 23 wells in Kansas were plugged at the State’s expense, out of 10,057 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 Bartlesville 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 | |---|---|---|---|---|---| | [Truman Investors, LLC 5-8](/search.md) API 15-121-28110 | Osborn Energy, L.l.c | Louisburg | 876 | 2005 | State | | [Bruce Schulz 3](/search.md) API 15-205-25536 | Dakota Production Co., INC | Neodesha | 780 | 2002 | State | | [Cook 3](/search.md) API 15-099-23162 | Double 7 Oil and Gas LLC | Mccune West | 150 | 2002 | State | | [Cook 5](/search.md) API 15-099-23169 | Double 7 Oil and Gas LLC | Mccune West | 150 | 2002 | State | | [Someday 29](/search.md) API 15-121-27520 | — | Paola-rantoul | 995 | 2001 | State | | [Someday 32-12](/search.md) API 15-121-27526 | — | Paola-rantoul | 900 | 2001 | State | | [Someday 35](/search.md) API 15-121-27528 | — | Paola-rantoul | 903 | 2000 | State | | [Arthur Mckaig 2](/search.md) API 15-091-22781 | Glaze, R.
