About this data

Norwegian Offshore Directorate (Sodir) FactPages, mirrored nightly and used under the Norwegian Licence for Open Government Data (NLOD). The Directorate files each core as an interval and nothing against it. The log places everything else on file for the wellbore inside the core whose interval contains its depth: photographs by the interval in their title, thin sections and slides by their depth, tests by overlap, formations by this wellbore's own tops. Core depths are driller's depths, so a mark at the very edge of a core can belong to its neighbor. Only slides made from core are shown; slides from cuttings at the same depths are on the Samples tab.
