Steps
Query wells with GET https://services.twdb.texas.gov/arcgis/rest/services/Public/WellReports/FeatureServer/0/query, passing standard Esri REST params: where=<SQL predicate>, outFields=*, f=json.
Filter by county, well use, or completion date using field names shown in the layer's metadata (append ?f=pjson to the layer URL) - this layer's supported query formats are JSON, geoJSON, and PBF, so pass f=geojson if you want GeoJSON directly instead of Esri JSON.
Respect the service's maxRecordCount of 2000 features per request; page through larger result sets with resultOffset/resultRecordCount.
This service covers the same TDLR Submitted Driller's Report data (Feb 2001-present, roughly 680,000 statewide records) as the Texas Water Data Hub's bulk pipe-delimited downloads, but lets you query live instead of downloading the full file.
For location-based queries, pass geometry + geometryType + spatialRel instead of, or combined with, a where clause.
Known gotchas
TWDB explicitly states well locations in this database aren't verified by state staff and may be inaccurate - don't treat coordinates as survey-grade.
The REST directory exposes Login/Get Token links implying write operations require credentials you won't have as a public consumer - stick to read-only query/queryDataElements, not applyEdits.
