Linked measurements and field data
Field and discovery production is shared context for linked wells; it is not this well’s production. Links use official identifiers; historical validity dates are unreported.
Record-level intelligence
These tools are descriptive: not forecasts, reserve estimates or investment advice. Source coverage is partial; unknown does not mean zero.
Offset wells
Nearest atlas records to the reported surface location, by great-circle distance. Records from different catalogues are not treated as the same physical well.

Thermal context
Nearest measured heat-flow sites (IHFC) and the source-reported bottom-hole temperature. Heat flow was not measured in this well; it is regional context.
- Measurement sites within 100 km

Opening the map connects to OpenStreetMap. Pins use WGS84 coordinates; accuracy varies by source. Zoom into clusters, then select a pin. Coincident records open a filtered list.
Partial source coverage. Status and company roles are reported by each source, not independently verified as current. Unknown does not mean zero.
Mapped from source purpose; not current activity or a prediction.
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.
