Refraction Statics using Tomography

Audience

Geophysicists in land processing (time and depth).

Content

2D and 3D refraction tomography are widely used in land processing.

The principles and fundamentals of tomography and how to build a near surface velocity model from first breaks using tomography is covered. Through hands-on exercises trainees learn the practical techniques to create a more reliable refraction models in challenging situations by optimizing the key processing parameters. QC is carried out using an interpretive workstation.

Learning Objectives

  • Describe how to build a near surface model using tomography.
  • Know how to QC the tomographic refraction model using an interpretive workstation
  • Understand how to improve the refraction model by optimizing the key module parameters
  • Create a reliable refraction model in challenging situations (noisy data, permafrost, gaps in  offsets, strong lateral velocity changes, etc.)
  • Improve refraction models using offset iterations

Duration

1/2-day

Number of Participants

6 - 10

Prerequisites

Trainees should have a basic understanding of the processing sequence
