From outcrops to seismic acquisition and interpretation

Présentiel

Domaine : Sciences de la mer - Thématique : Environnement marin, biodiversité et écologie marine

The training proposed below is a unique opportunity to gain practical experience of the whole process of acquiring, processing and interpretating marine geophysical data. Acquired data will subsequently be applied a simple and adapted seismic processing workflow presenting some of the fundamentals of seismic data processing, before being interpreted together with a set of pre-existing analogous seismic reflection profiles. The geological interpretation will finally be enriched with the integration of outcrop analyses. The exceptional geological context of the Alpes Maritimes area allows to study, compare and integrate observations coming from two comparable sedimentary architectures separated by only 40 km: at sea, the modern Var Turbidite System located in the Ligurian basin, and on the field, the fossil Contes/Peïra Cava sandstone formation that is part of the well-known and studied Annot Formation.

Public et pré-requis

PUBLIC AND PRE-REQUISITE

Public :
The training is for engineers and researchers involved at any stage of geological and/or geophysical interpretation.

Pre-requisite:
The training is dedicated to geologists interested in marine sciences, and more particularly wanting to acquire new skills in the field of marine geophysics and to geophysicists interested in marine sciences, and more particularly wanting to acquire new skills in the field of marine geology and sedimentology.

Programme

PROGRAM

Data acquisition:

Seismic acquisition at sea:
Acquisition of seismic profiles across the Ligurian margin and the modern Var turbidite system
Tests of acquisition parameters: effects on the quality of seismic profiles
Field geology:
Observation and analysis of proximal-distal architectures along the fossil Contes-Peïra Cava turbidite system belonging to the Annot Sandstone Formation (Eocene-Oligocene)
Observation and analysis of mass-transport and gravity-flow deposits
Acquisition of lithological logs.

Courses:

Principle of seismic-reflection methods: Conference
Resolution, signal penetration, artifacts and signal analysis on a seismic profile: Conference and Workshop
Numerical processing of seismic data: Conference and Workshop
Seismic interpretation of profiles collected in the Ligurian basin: Workshop
Turbidite systems and gravity-driven processes: Conference
Integration of seismic-profiles and outcrop observations: assets and limits of the two approaches: Workshop

Objectifs & Compétences

Goals

The aim of the training is:
1) to provide geologists –in particular those working on seismic interpretation– with an opportunity to get some better understanding of the whole chain of acquisition and processing of geophysical data.
2) to provide geophysicists working on acquisition, processing and/or interpretation of geophysical data with new skills in the field of geology, deep-sea terrigenous sedimentation, gravity processes and turbidite systems.

highlights

A marine seismic acquisition training unique in Europe.
A unique geographical location allowing minimal transit times to formations of great geological interest and maximizing acquisition times,
Recently renewed buildings and accommodation and teaching facilities at IMEV; spacious and well-equipped course and computer rooms.
A combination of marine acquisition, seismic processing, seismic interpretation, and unique outcrops to understand architectures and evolution of turbidite systems, in the exceptional setting of the French Riviera.

Pédagogie

Methods

The theoretical concepts are introduced during conferences (lecture courses) enriched with many examples and case studies that should allow participants to appropriate them. These courses will deal with the principles of seismic data acquisition, geophysical analysis and processing of seismic-reflection data, seismic interpretation, marine gravity-driven processes and turbidite systems, among others. Some case studies will be discussed in order to facilitate free interactions between the teacher-trainer and trainees.
