Porto basin: ca. 4.000 km2
Galicia basin*: > 6.000 km2
Lusitianian basin: 26.000 km2
Peniche basin: > 22.000 km2
Alentejo basin: > 13.000 km2

* within Portuguese waters
(mainly onshore)
(mainly off-shore)
The Lusitanian Basin, mostly onshore, is where the petroleum systems are best known, studied, proven and drilled, with no commercial discoveries. Other basins show some potential, a few wells have been drilled, but exploration needs to be improved.

1.ACCUMULATED KNOWLEDGE
• For decades, many academic geologists and
geophysicists developped scientific research on the
sedimentary basins and its stratigraphic infill.
• Research included aspects like Sedimentary Geology,
Stratigraphy, Structural Geology, Tectonics, etc., most of it
with no direct focus om Petroleum Systems.
• Most of this knowledge has been used for Oil & Gas
Exploration since the 50’s and particularly the 70’s - 80’s.
• Theres is therefore an important volume of academic
knowledge and publications (Thesis, Papers, Reports),
which is crucial to approach the Portuguese petroleum
Basins.
2. MAIN R&D FOCUS OF PORTUGUESE UNIVERSITIES

CONCLUSIONS THE ROLE OF UNIVERSITIES
IN HYDROCARBON EXPLORATION
a) Qualifying vintage and recent data, improving
technical knowledge, attracting industry attention
for Portuguese basins.
b) Training advanced students to become industry’s
young professionals.
c) Collaborating with industry in the development of
new interpretations and exploratory models.
d) Being part of the Portuguese exploration efforts in
Portuguese basins.
