Seismic Fundamentals for Non-Geophysicists
Jaap Mondt
40 hours
Business context
Various kinds of geophysical data are available. They are
separated into Seismic and Non-Seismic data. Seismic is, without
any doubt, the main method used in the oil and gas industry. But
Non-Seismic data (gravity, magnetics, electrical, electromagnetics,
spectral, etc.) is the main source of information in very shallow
subsurface applications (engineering, mapping pollution,
archaeology, etc.). In this course the fundamentals of seismic will
be dealt with.
Who should attend
Non-Geophysicists
Course content
We all have seen displays of seismic data in the form of
sections or cubes of data. But what do they show and how are they
acquired? In this course you will learn to understand that seismic
data represents the movement of the surface, resulting from waves
generated by a source, dynamite or vibrator, which are reflected by
changes in the subsurface rocks. Hence, what we record is related
to the properties of the rocks, not only rocks, but also its pore
fluids. All information on the subsurface is contained in these
recording, but almost impossible to extract and understand.
Therefor the records need to be processed to make it possible to
interpret structure and content of the pore space. In this course,
the basic principles of acquisition and processing will be
discussed. But also, insights in advanced methods will be provided.
These methods allow a much more accurate interpretation of seismic
data. The aim is not to fully understand these methods, but to
understand its importance in certain case, to enable interpreters,
reservoir engineers to formulate requests for these methods.
The above items will be dealt with in the course; by studying
background material and by making many practical exercises to
enhance the learning. In addition, you will benefit from Moodle
facilitating interactions with other participants and with
me.
Learning, methods and tools
The course uses a Blended Learning approach based on a
user-friendly Learning Management System, called Moodle. In Moodle
different modules provide study material, videos, and exercises.
The solutions to these exercises can be checked and if the exercise
is not clear or the solution cannot be found you can submit your
"solution" and ask for feedback. Also, each part contains a quiz
which is meant to reinforce the learning. The quiz consists of
multiple-choice questions. For each question, all answers can
be tried. The idea is that if the answer is not correct, one can go
back to the course material to find out what the right answer
should be. So, it is not an exam.
