Seismic Velocities and Depth Conversion

Seismic is recorded in time while wells are drilled in depth, and velocity variations can distort the apparent size and shape of a prospect. This course teaches how to combine velocity data with structural inputs to build or calibrate a consistent velocity model and convert interpretations to depth.

Who should attend

Early-career geoscientists and engineers, especially seismic interpreters, who need the basics of velocity modelling and time-to-depth conversion.

What participants will be able to do

  • Distinguish the main velocity types and their reliability
  • Combine and quality check velocities in an integrated model
  • Validate a velocity model against well ties
  • Convert horizons, faults and seismic data from time to depth

Topics covered

  • Seismic velocity types
  • Velocity model building
  • Time-to-depth conversion
  • Well tie calibration
  • Depth uncertainty
