Advanced Onboard Processing


Processing geophysicists having a basic knowledge and experience of onboard processing who wish to delve deeper and improve practice and awareness.


The course covers various aspects of seismic processing including SEG-D, and SEG-Y formats, and their generation, reformatting, quality controls for archive material.

Interactive tools are explored. Practical sessions allow for experience to be gained using an
Interpretation workstation. Participants will actively carry out various tasks including

- QC data using different tools provided
- Horizon picking
- Generation of horizon maps
- Velocity picking
- Interpretation

The theory and practice of 3D SRME by conventional modelling methodology is covered. Bin centering and regularization are presented together with the workflows.

Learning Objectives

• Know the main functionalities of the Interpretation Workstation and how to QC a 3D dataset
• Ability to pick horizons and velocities using an Interpretation Workstation
• Understand SEG-D and SEG-Y formats.
• Understand 3D SRME principles and methodology of convolutional modeling
• Be familiar with the methods used to regularize the trace distribution
• Describe the importance and method of Quality Control
