Petrel Geophysical Interpretation

The Petrel Geophysics course is designed to provide detailed hands on training to the user on the data visualization and volume rendering, mis-tie analysis, check shot data quality control and conditioning,sonic log calibration, synthetic seismogram generation, Reflection Coefficient (RC) modeling and wavelet generation, seismic attributes and techniques for specific geological environments, fault and horizon interpretation, and finally, introduction to velocity modeling and domain conversion aspects of Petrel Geophysics. 

The manual is based on Petrel 2018.1 release and will not include information about subsequent enhancements and modifications introduced in later releases. 

Day 1

Session 1: Modules 1, 2 & 3

  • 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 2Day 2: Modules 3, 4, 5 & 6

    • Seismic well tie preparation
    • Condition input data for Seismic well tie 
    • Sonic calibration 
    • Wavelet generation 
    • Synthetic seismogram generation
    • Tools for interpretation
    • Attributes and Techniques for specific geological environments


    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 review and get familiar with the tools and functionalities to start and perform seismic interpretation in optimal condition.

    Finally, typical and advanced seismic attributes and techniques available in Petrel and specifically adapted to three (3) different geological environments will be covered: channel, faulted, and salt environments. 



    Day 3

    Day 3: Modules 7, 8 & 9

      • Fault interpretation
      • Horizon interpretation and QC
      • 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.
