Oklahoma oil and gas operators

201,665 of Oklahoma’s 456,478 wells name no operator at all — the state files them to a placeholder rather than to a company — so the figures above count against the 254,813 that do. Oklahoma files the operator's NAME on each well and not its number. 120 names belong to two or more registered operators; the 4,732 wells filed under one of those names are left off every operator page, because the record does not say which operator they belong to.

The register also records each operator’s mailing address, phone number and named contact. This site publishes none of them — an operator page carries the company, its state number, its status and the city its office is in.
