Seismic Data Processing: Theory and Implementation
During the last decade seismic has become the key tool to exploration and development successes. With the advance of computer technology, processing has increasingly helped to acquire a competitive edge.
As there exist various ways to acquire seismic data and also a variety of objectives for which the data can be used it becomes clear that there is no standard procedure in seismic data processing. There is also a drive to extract more and more information from the data and therefore the scope for reprocessing. Seismic data processing can be characterized by a sequence of steps where for each of these steps there exist a multitude of different approaches. This course gives an overview of the steps that are common in seismic data processing and discusses for each step the variety of alternative implementations together with their inherent assumptions and strengths and weaknesses. This course enables participants to assess the impact of different processing methods with respect to the stated objectives.
Who should attend:
Geophysicists -acquisition, processing and interpretation- who are actively involved in seismic processing and/or liaise with seismic processing contractors. Geophysicists who are involved in special studies should have a thorough understanding of conventional processing.
Content of the program:
The following steps in seismic processing will be discussed:
Learning, methods and tools:
At the end of the course the participants will have obtained a thorough understanding and appreciation of the many alternative processing approaches that are commonly applied. They can act as processing geophysicist and/or liaise with the seismic processing contractor; they will be able to assess the implications of each particular processing route.
The course includes theory, exercises and examples from both synthetic and real data; 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.
