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.
