GEO-8126 Practical Seismic Processing 5 stp

Course content

The course will give a concise and practical treatment of the theoretical basis and philosophy for constructing each module in a typical seismic processing sequence, from loading the field data to the finished processed section. It provides a comprehensive overview of the steps that are commonly applied in seismic data processing and discusses their inherent assumptions, strengths and weaknesses. Through several practical exercises, participants will gain a working knowledge of the different processing methods and enable them to assess the quality of a processing result. The exercises will cover processing of a 2D seismic line, with documentation and reasoning for choosing processing parameters during the different steps.

Recommended prerequisites

GEO-3123 Marine Geophysics

Objectives of the course

Knowledge

The student has

  • a basic theoretical understanding of signal analysis of time series.
  • an understanding of the basic principles of seismic acquisition geometries that can be translated into the proper sorting and binning of the seismic data.
  • a theoretical understanding of the basic seismic processing steps: amplitude corrections, static corrections, frequency filtering, deconvolution, velocity analysis, normal moveout and stack, and migration.
  • the ability to identify random and coherent (e.g. multiple, ghost) noise in seismic data.
  • an understanding of signal-noise ratio.
  • an understanding of the role of processing, particularly seismic amplitude correction processes as pertains to subsequent interpretation.

Skills

The student can

  • develop and apply a typical seismic processing sequence including the proper parameterization of the individual processing steps.
  • identify acquisition artifacts as well as random and coherent noise in seismic data and devise a processing sequence to efficiently remove artifacts and improve signal-to-noise ratio.
  • conduct a velocity analysis of multi-channel seismic data and distinguish between the different seismic velocities (RMS, stacking and interval) as pertaining to the processing.
  • synthesize, explain and defend his/her seismic processing decisions through written and oral presentation and defense.

General competences

The student has

  • the capability to carry out an independent processing of seismic data.
  • overview of current research and new methods in seismic data processing.
  • the ability to carry out the most important elements of geological research projects: penetrating literature, analyzing data, and communicating results in written and oral form to fellow students/scientists.
  • the ability to work independently and/or in a team.

Language of instruction and examination

The language of instruction is English and all the syllabus material is in English. Examination questions will be given in English.

Teaching methods

A total of 40 hours of lectures and practical exercises.
