    This three-day hands-on training class provides students with the foundations needed to use the Petrel RTI tools in a full range of acquisition quality control, survey design, and imaging tasks. This course teaches how to create surveys for the different acquisition configurations, how to trace rays using different methods, create synthetic data, illuminate targets, and apply the results in seismic survey design, processing and imaging workflows.
    Day 1

    This class is suitable for geophysicists and geologists wanting to learn how to integrate the Petrel RTI tools into acquisition QC, survey design, and imaging workflows.

    At the end of the class students will be able to:

    -      Explain the different methods implemented within Petrel RTI to trace rays and in which situations each method could be used

    -      Create and/or import commonly used acquisition configurations into Petrel RTI: offshore NAZ, WAZ, FAZ; onshore orthogonal; VSP offset, walkaway, 3D

    -      Trace and display rays in Petrel RTI using different methods: ray shooting, two-points ray tracing, offset ray tracing, and opening angle ray shooting

    -      Use Petrel RTI to create synthetic datasets, illumination maps, validate models using checkshot ray shooting and estimate survey acquisition parameters

    -      Integrate Petrel RTI into data processing workflows (tomography, imaging)

    A knowledge and understanding of seismic theory, seismic & well data usage and limits, and basic ray tracing concepts. The student should be familiar with the key concepts of seismic survey design, acquisition, and processing.  Familiarity with basic Petrel functionality is essential and knowledge of the Seismic Velocity Model (SVM) Petrel plugin is recommended.
