3D Seismic Survey Design and Quality Control
(5 Days)

Course Description:
The overall objective is to introduce to acquisition and processing geophysicists and to seismic interpreters the key concepts and principles that form the technical basis for value added seismic applications in exploration, field appraisal and reservoir management. Learning objectives are at insight in the fundamentals and knowledge of the practicalities. Emphasis is on pratical understanding of seismic acquisition technical requirements for extraction of geophysical, geological and rock property information. Data examples, exercises and workshops are used to illustrate key concepts, practical issues and pitfalls as they affect seismic data quality and interpretation. The modular course design allows ready adaptation to shorter or longer versions and direct linkage to advanced treatment of specific topics.

Course Objectives:
  • classify types of seismic methods used in E&P
  • understand the role of seismic in the business of the reservoir cycle
  • explain the basic principles of seismic wave propagation
  • understand vertical and horizontal resolution of seismic data
  • understand factors that affect seismic amplitudes
  • understand the principles of marine and land seismic acquisition
  • explain the differences between seismic data and noise
  • understand the relationship between acquisition and processing of seismic data
  • determine the basic parameters that are used in the design of 3D seismic surveys
  • identify the major components of land and marine seismic data acquisition operations

Who should attend:
Geophysicists -acquisition, processing and interpretation- who are actively involved in seismic acquisition and/or liaise with seismic data acquisition geophysicists and/or operators.

Learning, methods and tools:
At the end of the course the participants will have obtained a thorough understanding and appreciation of the relationships between survey design and parameter choice and the stated objectives of the interpretation geophysicist. They can act as acquisition geophysicist and/or liaise with the seismic acquisition contractor; together with the processing geophysicist they will be able to assess the implications of the choice of survey design and acquisition parameters on objectives specified by the interpreter.
The course includes theory, exercises, workshops 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.
