GeoExperts: Advanced Training in Geophysics

Audience

Aimed at geophysicists who have a basic understanding of principles and practices in geophysics.

Content

Module 1: Seismic Acquisition and Processing 
The first week comprises a mixture of Powerpoint lectures and practical paper exercises. The emphasis is on marine seismic acquisition and processing with land data being only briefly covered. 
As well as the Powerpoint slides in paper form and on CD the participants are given a copy of Robertson’s Interactive Seismic Processing CD as part of the course. A binder containing copies of the processed marine seismic line from shot records through to final display is also provided. 
• Basic Reflection Theory 
• Acquisition methods
• Processing fundamentals and QC – 3 1/2 days 

Module 2: Introduction to Seismic Interpretation and Workstation Interpretation Before starting to interpret 

• Data inspection and evaluation
• Data display
• Seismic versus log resolution
• Well tops and check shot surveys
• Synthetic seismograms
• Choice of reflections
• Horizon selection

Pitfalls in interpretation
  
• Acquisition footprints
• Sideswipe and migration problems
• Multiples
• Tuning effects
• Velocity effects
• Diagenetic surfaces and gas hydrates
• Limits of interpretation packages

First stages of interpretation
