E-121 - Petroleum Systems: Hydrocarbons from Source Rock to Reservoirs

5 days GEO/GEOCHIM
Level
Foundation
Audience
  • Geologists, geophysicists or geochemists involved in petroleum potential evaluation or in reservoir management.
Purpose
  • To gain a greater understanding of important geological processes in a petroleum basin.
  • This course provides an understanding of various geochemical techniques, leading to sedimentary basins’ hydrocarbon potential evaluation and to the identification of hydrocarbon migration pathways.
Learning Objectives
  • Upon completion of the course, participants will be able to:
  • review the petroleum system concept and associated processes,
  • get practical insights of basic analysis of geochemical data and reports,
  • assess and analyze geochemical data in order to evaluate source rock potential and maturity.
Prerequisite
  • No prerequisites for this course.
Ways and means
  • Lectures and hands-on activities: several exercises and case studies.
