Basic Petroleum Geology
Consultant/Trainer: Lisa Thieme
Petrogenium (in collaboration with EPTS) Basic Petroleum Geology course participants will gain a comprehensive understanding of the subsurface, which is essential for making informed engineering and operational decisions. This knowledge helps optimize drilling operations, reduce risks, and improve safety by identifying geological hazards such as faults and overpressure zones. The training emphasizes the importance of integrated teamwork, ensuring participants appreciate how geology, drilling, facilities engineering, and economics must work together for successful field development.
Participants
Petroleum engineers, well-site engineers, geologists and geophysicists at the start of their careers.
Learning Objectives
At the end of the course participants will understand the principles of oil and gas generation, migration and trapping. They will be introduced the exploration processes and tools, learn the basics of rock properties, well log evaluation and log correlation. They will be able to apply geological concepts, construct maps and sections and use geological and geophysical data to make subsurface evaluations and to calculate oil and gas volumes.
They will learn how to prepare a well proposal and how to make a basic casing design based on subsurface pressures. They will understand the field appraisal and development process and will acquire practical experience by working on an actual field development plan in teams. Production facilities and costs will be briefly discussed, to allow economic assessment of their project at the end of the course.
