Dag Arild Karlsen

Roles and Affiliations: Dag Arild Karlsen is a Professor at the University of Oslo's Department of Earth Science, specializing in the Section for Environmental Geosciences. He holds a dual email address (d.a.karlsen@geo.uio.no and dakarlsen@geo.uio.no) and is based at the Geology Building (Sem Sælands vei 1, Oslo).

• Teaches GEO4211/GEO3211: Petroleum Systems
• Key research areas: Petroleum system analysis, organic geochemistry, and Arctic hydrocarbon exploration

Research Interests: Focuses on petroleum geochemistry of Arctic regions (Svalbard, Barents Sea), fluid inclusion analysis for reservoir history, and biodegradation processes. His work intersects with environmental geoscience, including shale gas discovery in Spitsbergen and postglacial plant colonization studies.

Publications Trends: Recent work emphasizes Barents Sea petroleum systems, Arctic source rock evaluation, and biomarker-based oil age determination. Over 100 peer-reviewed articles span topics like reservoir geochemistry, migration pathways, and North Sea hydrocarbon systems.

• Awards: 1993 Chemical Assoc. of America Best Paper Award for fluid inclusion-based reservoir filling research

Advising and Grants: Supervised 25 MSc and 7 PhD students. Conducted ~70 industry-funded projects for Norwegian oil companies, focusing on reservoir geochemistry and field filling dynamics.

Labs/Teams: Leads research in the Section for Environmental Geosciences, collaborating on projects like the 'Controlling Factors for Migration at Haltenbanken & Dønna.'
