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.
