A partner of excellence for oil and gas professional development

E-900 - Introduction to Petroleum Systems

5 jours GEOT/PETBAS
Niveau
Fondamentaux
Public
  • Oil and gas professionals, with little or no knowledge in geology
Finalité
  • To provide a comprehensive overview of petroleum geology processes (emphasizing basin geometry, deposition, hydrocarbons’ origin, migration, and accumulation) with an introduction to the ways and means of oil and gas exploration
Objectifs
  • To learn about exploration methods and tools, such as geophysics and well logging
  • To understand the factors required for the existence of an accumulation of hydrocarbons
  • To grasp the methodology used to assess the hydrocarbons potential of sedimentary basins
Les + pédagogiques
  • Field trip to Dorset (UK)
  • Outcrops
Observation
Course fees include accommodation and transportation during the field trip

Introduction
  • General introduction to petroleum geology
  • Place of exploration in the petroleum industry
  • Concepts and techniques used in petroleum exploration
  • Mechanisms of sedimentary basins formation
  • Infilling and deformation of sedimentary basins
  • Geophysical, geological, geochemical and wire line logging methods
Field trip
  • The field trip unfolds along the scenic cliffs of the south coast of Devon and Dorset
  • The two most important topics are:
  • Basin analysis (Weld and Channel Basin) from Permian and Tertiary times and building
  • Petroleum system of the neighboring Wytch Farm oil field:
  • Continental deposits (Permian): horst, graben and faults outcrops
  • Dawlish: alluvian fan and dunes deposition
  • Landram bay: braided rivers - Sherwood sandstones
  • Bridport sands: shallow marine environment and diagenesis
  • Langton Herring: limestones
  • Osmigton Mills: oil seepages
Conclusion
  • Last day: synthesis of all observations and introduction to reservoir characterization, using both geological and geophysical methods
