About this data

Norwegian Offshore Directorate (Sodir) FactPages, mirrored nightly and used under the Norwegian Licence for Open Government Data (NLOD). Tops are the Directorate's lithostratigraphy for the wellbore, in metres along the wellbore from the kelly bushing. A unit filed as No Formal Name or No Group Defined is the Directorate's placeholder where nothing is named.
