WCWO-E
 

                                                  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.
