Course description

Processing seismic data consists of applying a sequence of computer programs, each designed to achieve one step along the path from field tape to record section. Programs are usually used in a processing sequence, and these are selected from a library of several hundred programs. Each company’s library is unique, although many programs will be almost identical to those of another company.

 An overview of the best practices and the most recent seismic 2D and 3D seismic processing sequences used onshore and offshore will be provided. The participants will then learn the theoretical biases of the most important terms of seismic processing: the Fourier transform, time and frequency domain, convolution, cross and auto-correlations. The participants will then learn how to build an optimum processing sequence, in order to obtain the best data quality using the latest techniques. The mathematics of seismic data processing will be followed by the fundamentals of seismic data processing.

What will i learn?

• • The students should know how seismic data are acquired, processed and analyzed.
• • Understand the key steps in seismic processing, and know how the final processed data are used in exploring the earth's subsurface
• • Understand the basic theory and principles of seismic data acquisition, and how to assess critical acquisition parameters.
• • Understand how to derive and apply basic equations that are used in acquisition and processing of seismic data.
• • Understand how to perform a simple seismic processing of seismic field data. Fundamental procedures for how to mitigate environmental impact of data acquisition should be known.
• • Understand the basic principles used in seismic imaging, and realize similarities and differences to for instance medical imaging techniques.
