Objectives• Promote further exploration of the
Nova Scotia margin– Better understanding of the geology of
the offshore domain– New evaluation of the petroleum
potential– Improve data quality

Main questions to be answered
• What is the age of the different units recognized in the wells and on seismic lines?
• What is the role of the Jurassic salt in the structures and traps development?
• What is the evolution of the margin at crustal / lithospheric scale?
• Where are the reservoirs and sources rocks?
• What is the tectonic and thermal evolution of the Nova Scotia margin?
• ….
