Format and Duration
4 days

Summary

This workshop focuses on the geology and geophysics of salt basins and salt-related deformation. The content is centered around exercises interpreting a variety of seismic data illustrating some of the characteristic structural styles of salt basins. The exercises are supplemented by relevant lectures on salt tectonics and seismic imaging in salt basins. The class will help geoscientists to better develop and assess plays and prospects and to reduce costs by improving seismic interpretation skills.

Feedback

Great course, very comprehensive. Good balance of mechanics, models, real examples and geophysics. Instructors were engaging and motivating!

Duration and Training Method

A four-day seismic-interpretation workshop which will includes a mixture of lectures and seismic interpretation exercises.

Course Overview

Participants will learn to:

  1. Assess the limitations of seismic imaging for interpreting various salt-related geometries, including minibasin salt flanks and sub-salt targets.
  2. Analyse internal reflectors in salt bodies and their implications.
  3. Understand the relationships between crustal extension and evaporite deposition.
  4. Evaluate extensional salt geometries in both thin- and thick-skinned provinces.
  5. Assess the impact of salt on contractional deformation.
  6. Understand the different styles of salt evacuation and associated diapirism.
  7. Predict and interpret near-diapir deformation and how it influences three-way truncation traps against diapirs and welds.
  8. Evaluate the relative merits of different seismic migration techniques.
  9. Analyse and interpret complex allochthonous salt geometries and subsalt deformation.

The primary focus of the class is on the geology of salt basins and the geological interpretation of seismic data. Since an understanding of the geophysical aspects is also critical, the course also includes geophysical concepts and workflows and their practical implications for interpretation of migrated seismic data. The best practitioners, of course, combine a solid grounding in salt tectonics with a good understanding of the geophysical aspects.

  10. Exercise 8 – Building a salt model
  11. Exercise 9 – Allochthonous salt (Gulf of Mexico)

Geoscientists working in salt tectonic provinces, whether at the exploration, appraisal, development or production stage, as well as engineers with a decent understanding of structure and tectonics.

Elive Menyoli

Background
Dr. Elive Menyoli has nine years of industrial and academic experience.

After his graduation, Elive spent one and half year as a post-Doc with Applied Geophysical Research (OPERA) in Pau, France, and he later joined the Total SA innovative center in Pau, France. During this period he worked on topics such as surface related multiple attenuation, stereo-tomography and other imaging tools.

From 2003-2007 Elive was a Research Geophysicist with Total E&P Houston.  While with Total E&P, Elive conducted research in various areas of seismic depth imaging and complex salt velocity model building, with applications both in the GOM and Angola.

Since 2007 Elive has been in the Marathon Oil Corporation upstream technology group and he is currently a senior Geophysicist with the GOM Exploration team
