Course Description


This GLOMACS 2D and 3D Seismic Interpretation training course will focus on reflection seismic, one of the fundamental ways of imaging the subsurface from a geological perspective. 2D and 3D seismic data is a major source of information in the oil industry for both onshore and offshore activities.

Recently this type of data has also been used in geothermal energy activities, carbon sequestration in geological reservoirs and wind energy, especially offshore. Other uses include mapping salt structures for use as natural gas reservoirs (gas caverns), delimiting mineral deposits among other activities involving imaging of the subsurface.

This 2D and 3D Seismic Interpretation training course will cover the main concepts underlying the interpretation of 2D and 3D seismic data, from its History, the methods of data acquisition, processing, visualization and software. Several mapping exercises will be done using seismic data - faults and horizons - and how they can be used to understand the structure, stratigraphy and geodynamics of a basin.

The perspective of hydrocarbon resources will be addressed through reserve and associated risk calculation exercises.

This GLOMACS 2D and 3D Seismic Interpretation training course will highlight:

  • Seismic acquisition and processing
  • 2D and 3D data visualization
  • Fault interpretation and structural models
  • Horizon and stratigraphic interpretation
  • Petroleum systems, volumetrics and risking


At the end of this 2D and 3D Seismic Interpretation training course, you will learn to:

  • Understand seismic data acquisition and processing
  • Visualize seismic data and develop interpretation capacity
  • Interpret and map faults and seismic horizons
  • Identify hydrocarbon accumulations using seismic data
  • Quantify and risk hydrocarbon accumulations

Training Methodology

The training course will be based on slide presentations for each module, together with team and individual exercises. There will also be sessions with real exploration examples to get participants a hands-on experience on the usage of seismic data. Exercises and examples include several geodynamic settings and participants will be able to evaluate, quantify and risk hydrocarbon accumulations.

Organisational Impact

Seismic interpretation is a key tool in the Oil and Gas industry, from early stages of exploration to production. As such the organizational impact of this 2D and 3D Seismic Interpretation training course is reflected in:

  • Qualify staff with a key tool for the upstream industry  
  • Allow staff from different disciplines to have a common understanding of seismic data
  • Define company-wide seismic data standards
  • Boost staff capacity to correctly identify leads and prospects
  • Capacitate staff with skills to quantify and risk hydrocarbon accumulations
  • Refine the communication between geological evaluation and economic evaluation teams

Personal Impact

Seismic is the main source of subsurface data in the oil industry. Any Geoscientist or Engineer will need to at least be aware of its fundaments, uses and limitations. Personal impact includes:

  • Improve the knowledge on seismic data, how it is acquired, processed and interpreted.
  • Understand how faults, horizons and other features are interpreted and used for hydrocarbon exploration and production
  • Develop skills in identifying hydrocarbon accumulations using seismic data.
  • Ability to quantify and risk hydrocarbon accumulations
  • Communicate more efficiently with other geoscience and engineering disciplines that use seismic data.
  • Understand the wonders of geology imaged in the subsurface by seismic data


This 2D and 3D Seismic Interpretation training course is designed for subsurface professionals who are interested in using seismic interpretation for their work or interact with seismic interpreters in their companies.
