Name From the bird (English: puffin) of the same name.
Well type section Norwegian well 33/12-2 (Mobil) from 2951 m to 4048 m, coord N 61°13'31.38", E 01°51'25.97", (Fig 3.4).
Well reference section UK well 211/29-5 (Shell) from 3003 m to 4055 m, coord N 61°04'43.0", E 01°45'46.5" (Fig 3.5).
Thickness 1079 m in the type well, 1052 m in the reference well.
Lithology The formation is an interbedded sequence of very fine to very coarse-grained sandstones (2 to 10 m thick), claystones, marls and shales.
The sandstones are mainly white, pink or grey and cemented to a variable degree with kaolinite, anhydrite and carbonate. Fine-grained sandstones from the upper portion of the formation (core data from UK well 211/13-1) display small scale ripple cross stratification, bioturbation and incorporated mud clasts and mud balls. This part of the formation may also have small fining upward sequences.
The interbedded argillaceous units are dominantly red-brown clayst

About this data
Norwegian Offshore Directorate (Sodir) FactPages, mirrored nightly and used under the Norwegian Licence for Open Government Data (NLOD). Tops and cored lengths are the Directorate's, per wellbore and unit; the percentiles are computed from those tops and are depths along the wellbore, not true vertical depth.
