Courses

Participants will gain an understanding of depth-conversion methodologies, QCs for validating the methods employed, and tools for quantitative uncertainty estimation. They will also learn how to effectively design, guide, and QC depth-imaging projects in a variety of geologic settings and be able to: 

• Evaluate types of velocity data and methods for velocity definition and use
• Investigate the compatibility of well and seismic data
• Perform basic and advanced depth conversions of time data with uncertainty analysis
• Understand the key differences between time and depth migration
• Differentiate between ray and wave-equation methods
• Appraise the form of velocity updating (tomography/FWI) appropriate for the geology
• Establish a reasonable target velocity resolution for tomography
• Validate and correct the database via well top and seismic-interpretation ties 
• Plan and assess QCs for iterative velocity updates
• Appraise the methods used for determining anisotropic parameters
• Implement an optimal approach for calibrating well and seismic data
• Evaluate attributes such as inversion and (HTI) azimuthal stress and lithology estimates
• Review practical aspects of machine-learning classification and estimation

This course is of importance to geoscientists involved in seismic time interpretation, time-to-depth conversion, and the planning and interpretation of depth-migration projects. Participants should have a basic understanding of seismic processing and interpretation.

A basic background in geophysical interpretation, as well as some experience in time-to-depth conversion of seismic time horizons.
