About this data
Each state regulator's field and pool registry, with the completions and the reported volumes of each. The formation is read from the name the regulator gave it and matched to one registry shared by every state; a name that gives no single formation has none. Nothing is estimated.
Developers: this page as JSON is GET /v1/data/fields, documented in the API reference.
