E-416 - Geological Field Trip for Drillers

5 days FOR/FTFPE
Level
Discovery
Audience
  • Non-geologists and drilling professionals with no experience in petroleum geology.
Purpose
  • 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.
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 and to identify potential traps,
  • deduce implications for drilling campaigns.
Prerequisite
  • No prerequisites for this course.
Ways and means
  • Training includes classroom course with theoretical 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 constraints.
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 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 (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 turbidities 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 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.
