ICE FT 04 | Petroleum Systems of the Western Iberian Margin
American Association of Petroleum Geologists (AAPG)
Thursday, 12 October – Saturday, 14 October 2017, 8:30 a.m.–7:00 p.m. | Lisbon, Portugal
Who Should Attend
Geologists and geophysicists interested in looking at a fully outcropping North Atlantic passive margin and its Petroleum Systems.
Objectives
To learn about the long-lived evolution of an Atlantic Margin and the way its Petroleum Systems are originated and articulated within the geodynamic and paleogeographic regional framework.
Course Content
The Lusitanian Basin, located at the Western Iberian Margin, provides a unique opportunity to look at a completely exposed North Atlantic Margin. For over hundred million years, this basin suffered extension and subsidence, with two rifting phases and a break-up/drift phase, responsible for an over 5 km-thick sedimentary infill. Basin’s inversion related to the Alpine compression up-lifted large sectors, exposing the whole lithostratigraphic sequence. Different potential source-rocks and reservoirs are recognized in this basin and active petroleum systems with oil- and gas-shows have been studied and extensively drilled, with no commercial discoveries so far.
This Field-trip will present the three major Petroleum Systems (PS) of the Lusitanian Basin, each one named after its Source-Rock age: i) Paleozoic PS – Silurian and Carboniferous black-shales + Triassic siliciclastic reservoirs; ii) Lower Jurassic PS – Pliensbachian marine marls + Lower Cretaceous siliciclastic reservoirs; iii) Upper Jurassic PS – Callovian lagoonal marls + Upper Jurassic carbonate and siliciclastic reservoirs. The visit will be based mainly in extensive outcrop observations, including seismic-scale reservoir geometries, but selected seismic lines, well data and geochemical analysis will also be shown. Geodynamic evolution, basin architecture and salt tectonics (including seismic scale piercing diapirs) will also be presented and discussed.
