Course description

Salt Tectonics from Concepts to Application

This course covers all aspects of global salt tectonics. It discusses the origin and nature of evaporite basins and provides instruction on the essential elements of salt mechanics, diapirism, salt-related structural styles and salt-sediment interaction. Covered material ranges from fundamental concepts and practical application, to the influence of salt on petroleum systems. Lectures are complemented by exercises interpreting a variety of seismic data illustrating characteristic structural styles and evolutionary development of salt basins.

Suitability - Who should attend?

The course is intended for geoscientists who wish to strengthen their skills in evaluating salt basins around the world.

Outcome / Qualification etc.

  • Understand the implications of layered-evaporite sequences for velocity-model building and seismic interpretation.
  • Describe how halite differs from other lithologies and how that impacts deformation in salt basins.
  • Characterize the ways in which extension, contraction and differential loading trigger salt flow and diapir initiation/growth.
  • Evaluate how salt impacts deformation in different tectonic environments including rift basins, divergent margins and convergent-margin fold-and-thrust belts.
  • Interpret typical salt and stratal geometries associated with salt evacuation and diapirism.
  • Predict how drape folding around passive diapirs impacts stratal geometries, faulting, and reservoir distribution in diapir-flank traps.
  • Understand why and how allochthonous salt forms and how salt sheets/canopies evolve.
  • Assess the effects of salt on various aspects of the petroleum system, including trap formation, reservoir presence and quality, hydrocarbon maturation and migration, and weld seal.

Each day’s lectures will be supplemented by appropriate seismic-based exercises using 2-D and 3-D from worldwide salt basins.

Course delivery details

  • 9am-12pm CST
