Petrel Geophysics

The Petrel Geophysics course is designed to provide detailed hands on training to the user on the data visualization, frequency spectrum, mis-tie analysis, volume rendering, check shot data quality control and conditioning, sonic log calibration, synthetic seismogram generation, time varying wavelet, Gardner’s patching: auto-complete reflection coefficient inputs, Reflection Coefficient (RC) modeling, wavelet toolbox, fault and horizon interpretation, seismic reconstruction 2D and finally, introduction to velocity modeling and domain conversion aspects of Petrel Geophysics.

The manual is based on Petrel 2017.1 release and will not include information about subsequent enhancements and modifications introduced in later releases. For more recent releases, please refer to the Petrel Geophysical Interpretation course which covers all the topics in this Petrel Geophysics course, in addition to being based on Petrel 2018+ versions and introducing new learning subjects.

Day 1

Session 1: Modules 1, 2, 3 & 4

  • Project setup and data loading  
  • Data optimization and mis-tie analysis 
  • Seismic data visualization 
  • Seismic intersections and data manipulation


During Day 1, the participants will first be introduced to the process for setting up a new seismic interpretation project and loading seismic data accurately. Then, after reviewing the tools used to quality check the data, they will learn how to visualize and optimize the data imported and system performance. 


Day 2

Day 2: Modules 5, 6, 7, 8 & 9

  • Condition input data for Seismic well tie
  • Sonic calibration
  • Synthetic seismogram generation
  • Wavelet generation
  • Seismic attributes


Seismic-to-well tie is key at any stage of the development of a field. It is an essential step of the seismic interpretation workflow. In addition to bridging the gap between the time and depth domains, it also plays a key role in the wavelet extraction process involved in seismic inversion for reservoir characterization workflows.

Day 2 will begin with the theory, tools and methods for performing the sonic calibration process in Petrel. The participants will apply the procedures for checkshots data loading and quality control, well logs preparation for the seismic well tie workflow and time-depth relationships generation. Then, the participants will learn about generating synthetic seismograms and wavelets in Petrel. They will also cover the basics of seismic attributes.


Day 3

Day 3: Modules 7, 8 & 9

    • Fault interpretation
    • Horizon interpretation
    • Mapping and depth conversion


    This final session will focus on the techniques, functionalities, tools and procedures for interpreting horizons and faults in Petrel. The participants will also learn about mapping the horizons interpreted, basic velocity modeling and domain conversion in Petrel.
