Who should attend?

  • This course provides a practical understanding of petroleum systems, useful for integrating geological constraints and rock properties in drilling strategies which ultimately improve drilling models and reduce risk.
Public :
  • Non-geologists and drilling professionals with no experience in petroleum geology.

Level : Discovery

Course Content

  • INTRODUCTION TO PETROLEUM GEOLOGY

      • Basin and sedimentary rocks - Petroleum system:
      • Sedimentary basin - Definitions, structure and terminology.
      • Sedimentary rocks - Description and main facies - Comparison clastic versus carbonates - Sedimentary process.
      • Petroleum system - Source rock, reservoir rock and seal rock - Trapping and migration process.
      • Reservoir engineering: seismic, modeling, accumulations and reserves, effluent behavior, enhanced recovery (EOR), introduction to non-conventional resources and their extraction techniques.
      • Exercises: interpretation of geological cross section; identification of the petroleum components, petroleum system building; identification of potential prospects and implementation of exploration wells; analysis of limitations and drilling constraints.

  • FIELD TRIP IN THE PYRENEAN LACQ FIELD (active margin basin)

      • Presentation of the Lacq Basin. Relations with the Pyrenean structure:
      • Structural overview of the Pyrenean chain. Geomorphology and structural context.
      • Lacq basin: a petroleum system in the Jurassic, lower cretaceous carbonate domain. Source, reservoir and seal rocks.
      • Structure of the reservoir, trapping and potential hydrocarbon migration.
      • Sedimentary study of the upper cretaceous clastic formation:
      • The turbidites of St-Jean-de-Luz.
      • Detail of the sedimentary complex. Observation of the clastic deposits. Analysis of the deposit unit in a turbidite system observation and relationship with carbonate series of the Lacq field.
      • Analysis of the turbidites structure in St Jean de Luz. Syn and post sedimentary structures - Observation of “chair folding”. Dissymmetry of the folding. Notions of pressure/stretching and under compacted zones.
      • Comparison with turbidities facies of Gan (South of Pau) - Notion of lateral facies variation.
      • Synthesis and conclusions:
      • Structural context of the Lacq gas field: an example of active margin basin in foothills domain.
      • Elements of the petroleum system of the Lacq gas field: an example of petroleum system in carbonate domain.
      • The upper cretaceous turbidite system: interest of this facies analysis to understand the Pyrenean structure.
      • Field observation of the turbidite series structure: interest and consequences for drilling purpose.

Learning Objectives

  • Upon completion of the course, participants will be able to:
  • review main components of a petroleum system,
  • learn about most common facies rocks and their physical properties,
  • grasp the scope and fundamentals of the petroleum trilogy,
  • analyze deformations and constraints, identify potential traps,
  • deduce implications for drilling campaigns.
  • understand the importance of reservoir engineering.
  • become familiar with unconventional resources and their extraction techniques.

Ways & Means

  • Training includes classroom course with theoretical exercises and field trip observations in the Lacq gas province (Aspe valley - Pau, South-West of France) and on the Basque coast (Saint-Jean-de-Luz, Biarritz, Bidart - South-West of France).
