# Altavista Energy, INC — 1,163 Kansas wells on the register > 1,163 wells name Altavista Energy, INC as operator of record in Kansas. Which counties, how deep, and how many were plugged at the State's expense. ## Altavista Energy, INC **1,163** wells name this operator of record — 0.2% of the Kansas register, from 1997 to 2025. ### ⚠️ What this page is, and what it is not A count of the wells that name this company as **operator of record** — the operator the register carries, which is not necessarily the operator today, and not necessarily the one who drilled the well. Wells change hands and the register is not always caught up. It is **not** a rating and not an accusation. In particular, a well plugged at the State’s expense means the Commission could not find a responsible party at the time it acted — that is a fact about a file, not a finding against a named company. *Depth, over the 895 wells on this operator's records where a figure was reported (77%) — a median, never a mean* | Measurement | Median | 90th percentile | Kansas median | |---|---|---|---| | Total depth | **920 ft** | 1118 ft | 2831 ft — shallower here | ### What happened to these wells — on this operator's records **144** of the 1,163 wells on this operator's records are classed as plugged and abandoned. **0** were plugged **at the State’s expense** because no responsible party could be found, and **15** 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, 144 of these wells have a date on file.

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 *Altavista Energy, INC — 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 | |---|---|---|---|---|---| | [Marjorie Crotts I-34](/search.md) API
