Learn Seismic Data Processing

Basic 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.

What you’ll learn

  • Students will learn about the Elastic Theory and wave propagation.
  • Seismic Reflection Theory, sampling and Aliasing in time and space.
  • The course covers the key theories to ensure optimum data quality.
  • The participants will then learn the most important terms of seismic data processing techniques.
  • The students will understand the Fourier Transform and the Time and frequency Domains.
  • Participants will learn how to compute the static and the Dynamic corrections.
  • The course will include F/K Filtering, Migration and Multiple attenuation.

Learn Seismic Data Processing

Requirements

  • Basic knowledge of the geophysical methods especially the reflection seismic method.
  • It will be better if the participant have good idea about Seismic data Acquisition.

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 by 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 digitization, sampling, and how to avoid aliasing in the recorded data and during resampling in order to ensure optimum data quality. Mathematics of seismic data processing will be included as well. This 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 Sequence used onshore and offshore. The participants will then learn the theoretical biases of the most important terms of seismic processing: 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.
