Partial source coverage. Status and company roles are reported by each source, not independently verified as current. Unknown does not mean zero.
Boreholes and sidetracks may share a well ID. Counts describe these source snapshots, not market size. Catalogue labels describe the source, not territorial boundaries. Permitted locations may not have been drilled.

Sources and methodology
Public administrative records are normalized with stable source identifiers. Original operators, drilling contractors and reported owners remain separate roles. Dates describe source access or reported events; they do not establish live activity. Coordinates are transformed to WGS84 where needed. Confidential records and personal owner fields are excluded. See each source for coverage, attribution and reuse terms.
