Level 2: Reservoir Eng 5: Petroleum Geophysics and reservoir characterization
Objectives
At the end of the course participants will:
· Understand the fundamental concepts in geophysical exploration
· Grasp the potential of seismic data in terms of interpretation value
· Liaise and collaborate with experts in the fields of seismic acquisition, processing and
interpretation
· Place and value geophysical activities in a multi-disciplinary context
· Judge the merits of various geophysical techniques
· Recognize artefacts and direct hydrocarbon indications on seismic
· Value novel developments such as 4D and seismic inversion for exploration, development, and production purposes.
Participants will also work on field case seismic interpretation exercises both on paper & workstation.
A Handout containing a copy of the various presentations, together with some key
publications addressing key topics.
Several videos will also illustrate main topics.
