What was run in 25/2-8 and how the hole was built: the logs with their intervals, the casing strings with leak-off tests, and the mud at depth.

The table below says which logs were run and over what interval. The curves themselves are held in Diskos, Norway's national data repository; its public portal lists what has been released for a wellbore and can be ordered for an administrative fee. Diskos public portal →

The words under each tool string are Petrora's reading of the standard codes in it; a code we do not recognize is left as filed. The composite log is one file for the whole well. The Directorate does not say which runs or depths it draws on, so the link is the same on every row.

About this data

Norwegian Offshore Directorate (Sodir) FactPages, mirrored nightly and used under the Norwegian Licence for Open Government Data (NLOD). Log names are the Directorate's tool strings as filed; the plain-word readings beside them are Petrora's, from common industry abbreviations. Depths are metres along the wellbore from the kelly bushing; diameters are inches, as filed.

Developers: this page as JSON is GET /v1/data/norway/wells/131, documented in the API reference.
