Practical Seismic Attributes with Petrel

In this course the students learn the theory and practical workflows needed for effectively using post stack seismic attributes in seismic interpretation.

The course content covers the most common seismic attributes, discusses the theory, attribute management and visualization. It delivers concepts and workflows for the interpretation of stratigraphy, structure, direct hydrocarbon indicators and discusses clastic, carbonate and reservoir features. 

The students learn these concepts and workflows while guided by well-structured exercises done in Petrel and based on a variety of seismic datasets.

This course will outline the practical aspects of generating and understanding Seismic Attribute responses and relating these from the mathematical geophysical generation to practical geological understanding and application.

Focus will be placed on outlining the use of seismic attributes in specific geological environments and identification of specific geological features.

The Learning Objectives for the course are

  • Teach the theory of seismic attributes
  • Teach the practice of seismic attributes using example sessions with Petrel software
  • Prepare you to use seismic attributes in your work

    Day 1

    • Short History and Theory of Seismic Attributes
    • Seismic Attributes in Petrel
    • Colors and Visualization of Attributes
    • Surface Attributes in Petrel
    • Noise Reduction
    • Fault Interpretation (Edge Detection)
    • Fault Interpretation (Edge Enhancement)

    During the first part of the day the students learn the basic theory and concepts of seismic attributes. Different visualization techniques are covered using Petrel including color and opacity management and co-rendering of different seismic attributes (RGB display mode).

    During the second part of the day the students learn using seismic attributes for noise reduction and the workflow for fault interpretation based on a combination of seismic attributes. The resultant cube highlights faults against the seismic background dramatically and is ready to be used for accurate manual or automated interpretation.

    Day 2

    • Stratigraphic Interpretation
    • Channel Interpretation
    • Textural attributes
    • Fracture indicators

    On day two the students learn to use seismic attributes to highlight stratigraphic terminations and sequence boundaries and apply them on a data set to perform the seismic stratigraphic interpretation.

    After this the students learn to apply seismic attributes and techniques to highlight channels and sedimentary features in clastic sedimentary environments and their interpretation using probes and geobodies.

    Then the students learn how to use textural seismic attributes to separate sedimentary features based on their texture.

    Finally the students review some of the attributes commonly used for fracture detection.             

    Day 3

    • Carbonates
    • Salt
    • Direct Hydrocarbon Indicators (DHI)
    • Seismic calculator
    • Group project

    During this day the students review the seismic attributes and techniques used for Carbonate seismic interpretation with emphasis on karst features.  It follows a review of the seismic attributes and techniques to highlight salt features and their interpretation.

    Then the students review some seismic attributes commonly used as direct hydrocarbon indicators. They will use the seismic calculator to highlight features in their seismic data, merge seismic volumes and create new seismic attributes.

    The day concludes with a group project where the students   use the concepts they learned during the course to perform an interpretation challenge based on a seismic data set.
