Structural Geology, Basin Development & Associated TrapsMETH/STRUCT

Who should attend?

  • This course provides an in-depth knowledge of key elements which characterize the structural style of a sedimentary basin.
Audience :
  • Petroleum exploration geoscientists, multidisciplinary team managers.

Level : Foundation

Course Content

  • PLATE TECTONICS & STRUCTURAL STYLES

      • Earth structure, global dynamics and time scales.
      • Structure of continental and oceanic lithospheres: thermicity, rheology, stress and strain.
      • Fundamentals of structural analysis:
      • Extensional regimes: geodynamics and architecture of related basins (rift basins, passive margins).
      • Compressional regimes: geodynamics and architecture of related basins (foreland basins, active margins, thrust belts).
      • Intra-plate basins and tectonic inversion.
  • EXTENSIONAL & COMPRESSIONAL DEFORMATIONS - STRUCTURAL TRAPS

      • Structural traps in extensional context.
      • Structural traps in compressional context.
      • Wrench faulting and related traps.
      • Salt tectonics and related traps.
      • Relationship between tectonic and sedimentary processes.
      • Case study: the Arabian plate and margins, relations with petroleum systems.
  • EXPLORATION & DEVELOPMENT PROBLEMS ASSOCIATED WITH STRUCTURAL STYLES

      • Folding mechanisms and styles, impact on fractures distribution.
      • Conductive and sealing faults.
      • Migration pathways and petroleum systems timing.
      • Seal efficiency and time of residence of hydrocarbons in structural traps.
  • SUMMARY, SYNTHESIS & WRAP-UP

Learning Objectives

  • Upon completion of the course, participants will be able to:
  • get familiar with both brittle and ductile deformations identification and analysis, in various types of sedimentary basins, at different scales and under different stress regimes: at lithosphere scale: plate tectonics and basin formation (rifts, passive margins, active margins and thrust belts); at basin scale: subsidence and inversion, structural traps (tilted blocks, horsts, shale and salt domes, folds), at field and reservoir scales: behavior of faults (seal or drain), fracturing, cap rock integrity…,
  • be able to identify the specific structural style of a petroleum area, on outcrop pictures and on seismic profiles,
  • be able to grasp issues linked to tectonic evolution versus petroleum system evolution (in different structural contexts).

Ways & Means

  • Interactive course: lectures illustrated by practical exercises and personal work.
