About this data

Norwegian Offshore Directorate (Sodir) FactPages, mirrored nightly and used under the Norwegian Licence for Open Government Data (NLOD). The Directorate files a core as an interval and nothing against it. Everything else on this page is on file for the wellbore and is shown here because its depth falls inside the core's interval: photographs by the interval in their title, thin sections and slides by their depth, tests and logs by overlap, units by this wellbore's own tops. Core depths are driller's depths, so a mark at the very edge can belong to the neighboring core. Reports are filed for the well, not for one core.

Developers: this page as JSON is GET /v1/data/norway/wells/43/cores/1, documented in the API reference.
