E-416 - Geological Field Trip for Drillers

5 days FOR/FTFPE
  • Non-geologists and drilling professionals with no experience in petroleum geology
  • To provide a practical understanding of petroleum systems that is useful for integrating geological constraints and rock properties in drilling strategies which ultimately improve drilling models and reduce risk
Learning Objectives
  • To review main components of a petroleum system
  • To learn about most common facies rocks and their physical properties
  • To grasp the scope and fundamentals of the petroleum trilogy
  • To analyze deformations and constraints, and identify potential traps
  • To deduce implications for drilling campaigns
Ways and means
  • Training includes exercises and field trip observations in the Lacq gas province (Pau, South-West of France)

Introduction to petroleum geology 2 days
  • 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
  • Exercises: Interpretation of geological cross section, identification of the petroleum components, petroleum system building - Identification of potential prospects and implementation of 2 exploration wells - Analysis of limitations and drilling constrains
Field trip in the Pyrenean Lacq field (active margin basin) 3 days
  • Presentation of the Lacq Basin - Relations with the Pyrenean structure
  • Structural overview of the Pyrenean chain - Geomorphology and structural context
  • Lacq: a petroleum system in the Jurassic - Lower cretaceous carbonate domain - Source, reservoir and seal rock
  • 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 (Bouma sequence) observation and comparison 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 (laminated flanks) and under compacted zones
  • Comparison with turbidites facies of Gan (South of Pau) - Notion of lateral facies variation - Conclusion
  • 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 turbidites system: interest of this facies analysis for understanding of the Pyrenean structure
  • Field observation of the turbidite series structure: interest and consequences for drilling purpose
