What does wildcatted mean?
“Wildcatted” is chiefly a North American petroleum term. As a past-tense verb, it means that an exploratory oil well was drilled, usually in territory not already established as a producing field; as a participial adjective, it describes the well, field, or operation created by such drilling. The word comes from “wildcat,” a compound associated with wild animals and later used for risky or independent prospecting. In modern usage, “wildcatted” often carries the high-connotation sense of frontier drilling: a venture undertaken away from known reserves and without the assurance of commercial production. It can therefore imply speculation, independence, and technical risk, even when the drilling itself has been completed successfully. The older hunting sense of “wildcat”—tracking or hunting wild animals—also survives in the verb’s inflected forms, though it is much less frequent today. The term is especially associated with the history of North American oil exploration, where exploratory drilling was often described as “wildcatting.” Despite its specialized modern history, “wildcatted” remains intelligible as the past tense and participle of a familiar verb while preserving the romantic idea of venturing into unknown territory.
To drill exploratory oil wells, especially in territory not known to contain oil; more rarely, to hunt wild animals.
"The prospectors wildcatted a promising site after the geological survey was completed."
The petroleum sense dominates modern usage. The hunting sense is older, literary, and uncommon.
Of or relating to an exploratory oil well or drilling operation conducted outside established producing areas.
"The abandoned wildcatted well produced no usable petroleum."
This participial use is especially associated with historical oil-exploration writing.
A well drilled where the map said “probably nothing”—that is the frontier spirit of “wildcatted.”

Etymology of wildcatted
Wildcatted is the regular past tense and past participle of wildcat, an English compound of wild and cat. The compound long predates the petroleum industry, and its mining and drilling sense developed from the idea of an independent, risky venture into unexplored territory. Wildcatted itself is therefore a modern inflection, not a separate inherited word, and its immediate relatives are the forms of wildcat.
