Business Applications in Seismic Data Processing
(duration: optional)

Business Context:
The processing of seismic data nowadays serves a variety of objectives. These depend very much on the state of the prospect, - exploration and reconnaissance or appraisal and development - , and on the available data. In addition to conventional (3D) surface seismic data there is multi-component data, acquired on the surface or on the sea bottom, seismic data (multi-component) from boreholes (VSP and hole-to-hole) and well log data (e.g. sonic and density logs). Also increasingly, seismic data is being used in combination with data from petrophysics, geology and reservoir engineering (imaging below salt, production seismology, seismic inversion, lateral prediction, fracture orientation and density, lithology and/or pore fill discrimination, time-lapse (4D) studies) allowing advanced ways of reservoir modelling and field management. Depending on the type of problem and need of the client, emphasis may be placed on the following courses:
  • Digital signal processing - theory
  • Seismic data processing
  • Advanced topics in seismic data processing
Each of these courses may be selected as a separate 5 day module. It is also possible to select any topic or combination of topics that one considers appropriate for its own learning goal. Each module, e.g. anisotropy or AVO, typically requires half a day. This way there is flexibility in the selection of topics as well as in the duration of the course.
Examples of combinations of pairs of topics that require a full day are:
  • Multi-component seismic + anisotropy
  • Wavefield extrapolation + migration algorithms
  • Signal-to-noise enhancement + multiple elimination
  • Velocity model building + migration
  • AVO + seismic (elastic) inversion
  • Seismic reservoir characterisation
  • Least-squares estimation + deconvolution techniques
For additional information about the content of this course see Details.

Who should attend:
Geophysicists -processing and interpretation- who wish to enhance insight in specific subjects, in order to improve integration of seismic data and interpretation in reservoir modelling and management.

Learning, methods and tools:
At the end of the course the participants will have a representative and up to date understanding of the selected toipic(s). He or she is fully capable to participate in existing and follow new developments in these fields. The course includes theory, exercises and examples; a handout that covers all course material will be made available.

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.
