About this data

Wyoming Oil and Gas Conservation Commission: the latest APD on each well record, with its approval date, the formation and depth the operator proposed, and the well's spud date where one is on file. A well whose APD was re-approved appears once, under its latest approval. Nothing is estimated.

Developers: this page as JSON is GET /v1/data/permits?state=wy, documented in the API reference.
