Multi-state companies

A regulator registers an operator inside its own state, under its own number. A company here is Petrora's grouping of registrations: those filed under the same name from the same city, and those linked after review, so one company's wells in every state can be read together. The grouping is ours, not a regulator's record.

About this data

Operator registrations from each state regulator, grouped by Petrora: registrations filed under the same name (punctuation and corporate suffix aside) from the same city are one company; anything else is joined only by a curated correction. A subsidiary filed under a different name is not matched. Tell us where a grouping is wrong at [email protected].
