Development Geology
Consultant/Trainer: Evert Uitentuis
The Petrogenium (in collaboration with EPTS) Development Geology course will provide participants introduction to “Development Life Cycle” starting with the gathering of geological data, the interpretation thereof, the preparation of geological models and the quantification of subsurface uncertainty are discussed. The development geologist is equipped with the skills to construct these models. Attention is given to the impact on field operations and on field management during its entire lifecycle.

Participants
This Petrogenium course is aimed at Petroleum engineers and geologists involved with exploration and development of oil and gas reservoirs. Participants need a basic understanding of Reservoir/Petroleum Geology and preferably some 2 – 4 years experience.
Learning Objectives
At the end of the course participants will apply geological concepts, construct maps and sections and validate computer-generated interpretations.
- be able to calculate subsurface volumes and assess the uncertainties.
- learn about the contents of a well proposal.
- be able to plan appraisal wells and assess their economic value.
- acquire practical experience by working on an actual field study in teams
- better understand their own role in the development life cycle.
