Learn Seismic Data Processing

Learn Seismic Data Processing

Seismic data is recorded in the field on magnetic tape. About three to six weeks later, the information is transmitted to the interpreter as a seismic section.

All of the intervening steps comprise the data processing phase of seismic exploration.

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.

In each company’s library, there may be several programs designed to produce the same effect through different approaches. For example, one program may operate in the time domain while another works in the frequency domain, yet they may yield similar results.

The course also covers seismic waves propagation & seismic records data digitalization, sampling and how to avoid aliasing in the recorded data and during resampling in order to ensure optimum data quality. The mathematics of seismic data processing will be followed by the fundamentals of seismic data processing. 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.
