Salt Tectonics: Global Styles, Spanish Outcrops (Basque-Cantabrian Pyrenees, Spain)

Course Code: N232
Course Outline:  Download
Format and Duration:
5 days

Summary

In the Basque-Cantabrian Pyrenees, both field exposures and seismic data illustrate thick- and thin-skinned salt structures, extensional and contractional diapirs, halokinetic deformation involving turbidites, and allochthonous salt, in a passive-margin setting subsequently subjected to convergent-margin tectonics. This course covers the fundamentals of salt-related deformation and salt tectonic styles around the world, and includes global seismic interpretation exercises.

Business Impact: Participants will develop an understanding of global salt tectonics and its practical application to petroleum exploration, production, and storage.

Feedback

"Great course - I would recommend it to all experience levels in salt tectonics. Everyone can take something away from the course! I also really enjoyed the Bakio Salt Diapir with its interaction between salt and turbidites."

Duration and Training Method

This is a combined field and classroom course, in a 60:40 ratio. Classroom sessions will comprise lectures, global case studies, and seismic interpretation exercises.

Course Overview

Participants will learn to:

  1. Characterise the depositional and tectonic settings of layered evaporite sequences.
  2. Understand the influence of different modes of salt tectonics on intrasalt deformation.
  3. Assess the role of salt in different tectonic environments including rift basins, passive margins and convergent margins.
  4. Evaluate salt structures developed or reactivated during extension, contraction and strike-slip deformation.
  5. Appraise and interpret the stratal geometries associated with salt evacuation and passive diapirism.
  6. Predict near-diapir stratal geometries and their impact on reservoir distribution.
  7. Characterise allochthonous salt geometries on seismic data and evaluate the nature of subsalt deformation.
  8. Evaluate the interaction between salt-related deformation and sedimentation in different depositional environments, from fluvial to deepwater.
  9. Appraise the likely influence of salt bodies and salt welds on hydrocarbon generation and migration and top seal for hydrocarbons and hydrogen.

Classroom modules will address the theory of salt-related deformation, compare to field analogues from elsewhere in the world, and review subsurface data and interpretation from major petroleum basins. Examples include the North Sea, Precaspian Basin, Persian Gulf and Zagros Mountains, eastern Mediterranean, offshore West Africa, offshore Brazil, and the Gulf of Mexico.

Lectures will cover: the tectonic setting of salt basins and the nature of layered evaporite sequences; the mechanics of salt movement; intrasalt deformation; extensional and contractional salt tectonics; salt evacuation and diapirism; near-diapir deformation; the emplacement and evolution of allochthonous salt; salt-sediment interaction; the impact of salt on hydrocarbon maturation, migration and seal.

Field modules will focus on those Cantabrian examples where there is the widest variety of salt styles and sediments. Depositional environments include sub-aerial, shelf clastics and carbonates, and deepwater turbidites. Diapirs were triggered during extension, grew passively, and show different degrees of reactivation during the Pyrenean contractional event. Field examples will be supplemented by seismic and well data over mildly reactivated diapirs offshore in the adjoining Bay of Biscay and over onshore Cantabrian salt structures where they are the focus of research programs for gas storage, carbon sequestration, and hydrogen storage. Cantabria is one of the few areas in Spain in which oil exploration is still active and storage opportunities are being pursued.

Josep Anton Munoz

Background
Josep Anton Muñoz is professor of structural geology at the University of Barcelona and head of the Geodynamics and Basin Analysis Research Group.

He worked for the Servei Geològic de Catalunya from 1985 to 1990, when he joined the University of Barcelona. His research interests include the structure of sedimentary basins in different tectonic settings (contractional, extensional and strike slip), tectonics of orogenic systems, tectono-sedimentary relationships, salt tectonics, and construction and validation of 3-D structural models. He has mostly worked in the Pyrenees, but also in many other areas such as the Alps, Andes, Antarctica, Betics, Morrocco Atlantic margin, Flinders Ranges, Gulf of Mexico, Hellenids, Tanzania and Zagros Mountains. His research is based on field studies and their integration with seismic and well data. He has led the development of new methodologies for the 3D construction of structural models ant their validation combining numerical and analogue models. He has conducted many research projects and courses (both field and indoor) for oil companies and international research institutions. He has over 260 published papers, half of them in SCI international journals. He was awarded in 2006 by the Generalitat de Catalunya as a Distinct Researcher.

Eduard Roca

Background
Dr. Eduard Roca possesses over 25 years of industrial and academic experience. After graduating Eduard completed a PhD thesis in collaboration with the Institut Français du Pétrole on the structure of the Valencia Trough (Western Mediterranean).

In 1992, Eduard spent a year working at the Institut Français du Pétrole as a research fellow. While in Paris, Eduard conducted research into hydrocarbon exploration in the Outer Carpathians, paying special attention on the relationships between thrusting and the pre-existing structure.

At the beginning of 1993, Eduard rejoined the University of Barcelona, where he has remained since, first as an assistant, then in 2002 as a professor of Structural Geology in the Department of Geodynamics and Geophysics.  During this time, he has taught undergraduates and graduates structural geology, basin analysis and geological cartography, and advised graduate students in structural geology, basin analysis, 3D geological reconstructions and salt tectonic projects. Often in collaboration with oil companies, Eduard’s research projects have been drawn from Europe, South America and North Africa. Also, since 2002, Eduard has conducted training courses on structural geology and salt tectonics for Total, Repsol and the Nautilus Geoscience Training Alliance.

Present-day Eduard’s primary interests are salt and inversion tectonics although he continues working in 3D reservoir reconstructions, tectono-sedimentary relationships and the characterization of extensional and contractional fault systems.
