Non-Seismic Data Acquisition and Processing
Jaap Mondt
5 days
Business context
Seismic is the main subsurface evaluation tool for the EP
industry. But seismic has its limitations and non-seismic
techniques like Gravity, Magnetics and Electro-Magnetics can be
used successfully as complementary tools in subsurface evaluation.
In combination with seismic data they can significantly reduce the
uncertainty of subsurface models because they measure different
physical properties of the subsurface. Controlled Source EM for
example responds to reservoir resistivity and can thus be used to
differentiate between alternative porefill scenarios.
Who should attend
Geologists and Geophysicists involved in acquiring, processing
and interpreting geophysical data for subsurface evaluation.
Course content
The course aims at providing participants with the necessary
foundation to be able to contribute to acquiring and processing
Gravity, Magnetic and Electro-Magnetic data and to assess what
value such data can add. Ways in which such data can be integrated
together with seismic and how to avoid common pitfalls will be
discussed as well.
The following topics are covered:
- Benefits and limitations of seismic data
- Gravity
- Magnetics
- Electromagnetics
- Controlled Source marine Electro-Magnetic methods (CSEM)
- Magneto-Tellurics (MT)
- Combining the various physical quantities in
interpretation
- Industry and Participants case studies
Learning, methods and tools
At the end of the course participants will have a good
understanding what non-seismic data can add to the seismic
information, and how to acquire, process, interpret such data
in an integrated manner. They can better liaise and collaborate
with staff in neighbouring Geoscience (sub)disciplines. It aims at
providing conceptual understanding without going into mathematical
detail. The course uses a mixture of lectures and practical
exercises, complemented with some case histories. Use of
participants laptops for exercises and WIFI internet access in the
classroom is recommended. The course can be customized to meet
specific needs of participants.
