2 Norwegian Interactive Offshore Stratigraphic Lexicon Industrial mandate to update the 25 year old and boring NPD Lithostratigraphic Bulletins # 1- 5 …1600+ wells reported with Formations… Industry - Academia Consortium funded by 50+ companies and NPD Since 2005, twelve workshops with NPD, oil companies, NGU and universities and over 25 working meetings. Over 75 scientists have participated, with a core of 7 people.
