Search FracFocus well-level frac job disclosures by state/county/operator.

Tool description as the model sees it

Hydraulic fracturing job disclosures (wells) from FracFocus, the national frac-chemical disclosure registry — filter by state, county, and/or operator name (operator matches as a substring, case-insensitive). Returns each well’s API number, operator, well name, location, job dates, and base fluid volumes, newest job first. Covers FracFocus’s full disclosure history (back to its earliest submissions, most of it from 2011 on). Pass the API number from a result into frac_chemicals to get that job’s chemical ingredient list. At least one of state, county, or operator is required — an unscoped scan of ~250k disclosures is not supported.

Parameters

Name	Type	Required	Description
`state`	string	yes	US state name, e.g. “Texas” (full name, case-insensitive; FracFocus stores state as a name, not a postal code).
`county`	string	no	County name, e.g. “Martin”. Case-insensitive exact match.
`operator`	string	no	Operator name, substring match, case-insensitive, e.g. “Pioneer”.
`limit`	number	no	Max rows, 1-200. Default 50. A truncated response carries truncated:true, total_matching, and a hint for narrowing.
`offset`	number	no	Pagination offset. Default 0.
