NSTA — UK offshore wellbore top holes

Each dataset retains its source, access date, row count and reuse conditions. Filtered NDJSON is available for algorithm development.

Matching records: 13,383
Distinct source well IDs: 8,295
Source catalogues: 1

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.
