Petroleum Geochemistry
Consultant/Trainer: Julian Moore
The Petrogenium (in collaboration with EPTS) Petroleum geochemistry course will guide the participants with the necessity of integration between geochemistry and geology. The prediction of fluid type (oil or gas) and volumes generated in the basin, or present in un-drilled traps, relies a.o. on the understanding of petroleum systems. Geochemistry can provide key data to build a reliable petroleum systems model, and thus helps to rank prospects and to minimise exploration risk. This course teaches the fundamentals of the geochemical tools, and demonstrates the potential of geochemistry in hydrocarbon exploration.
Participants
This Petrogenium course aims at Petroleum geoloscientists involved with exploration & production of hydrocarbons.
Learning Objectives
At the end of the course participants will have gained insight into the main geochemical concepts, tools, and application domains. They will understand how geochemistry can contribute to solving exploration and production problems. Exercises are used to reinforcing the acquired knowledge in a practical context. The participants will be able to apply basic geochemical tools, and will be in a position to define and manage geochemical projects.
