(5 Days)
Business Context:
This course gives a thorough introduction to the theory of digital signal processing. Special attention will be given to the digital processes that are relevant for seismic data processing. This course should be considered as an introduction to the subsequent courses "Seismic Data Processing" and "Advanced Topics in Seismic Data Processing". As data acquisition, processing and interpretation will become ever more interrelated, this course and the subsequent courses are presented in such a manner that the more physics inclined as well as the more geology inclined earth scientist will benefit.
Who should attend:
Geophysicists -acquisition, processing and interpretation- who are not already familiar with the theory and who intend to familiarize themselves with seismic data processing via subsequent courses. Depending on the level of prior knowledge with the participants, the length of the course can be either 5 or 10 days.
Content of the program:
Digital Signal Processing Theory, i.e. the theory that underlies digital processing, has the following chapters:
- Complex calculus
- Fourier analysis
- Laplace transform
- Linear system theory
- Sampling theory
- Z-transform
- Stochastic processes and least-squares estimation
- Inverse filters and least-squares filter design
- Digital filter design
- The two-dimensional Fourier transform
- Multi-trace filtering
- Transforms
Learning, methods and tools:
At the end of the course the participants will have obtained a thorough understanding of the theory that underlies digital signal processing; moreover they will be optimally prepared to attend the subsequent courses on seismic data processing. The course includes theory, exercises and examples derived from relevant seismic processing cases; a handout that covers all course material will be made available. During the course there will plenty of time for interaction.
About the trainer
Piet Gerritsma (1942) graduated in physics at the University of Groningen. He joined Shell in 1969 as a research geophysicist in Rijswijk (The Netherlands) and Houston (USA). He was actively involved in the development of programs for statics, velocity analysis, synthetic seismograms and raytracing, deconvolution, multi-component seismic, shear waves and anisotropy, AVO and migration. He acquired operational experience as processing and special studies geophysicist in Brunei and in Canada. He was Shell's representative in international research consortia: SEP (Stanford), DELPHI (Delft University of Technology) and IFP (Institut Francais du Petrole); he also served as associate editor of Geophysical Prospecting on Migration, Modelling and Inversion. During his Shell career he has always lectured at both basic as well as advanced level covering a broad range of topics. He left Shell in 1999 after 30 years of service.
Since that time he is a lecturer at CTG (Center for Technical Geoscience) at the Delft University of Technology. He is represented with two courses in the educational program of the EAGE. He teaches regularly courses for national and international oil companies and service companies both as an independent teacher as well as on behalf of geoscience training alliances.
