Advanced Seismic Field Acquisition Techniques

 

Instructors: Albin Krekes / Alam Lembang.

 

Locations: Houston, Texas / London, UK / Dubai, UAE / Kuala Lumpur, Malaysia.

 

Who should attend?

The course is recommended for Exploration Managers, Geologists and Geophysicists involved in the acquisition, processing and the interpretation of seismic data.

 

Course Description:

This four-day course will provide an inside view of fundamental concepts, methods and equipment used in seismic field acquisition as it relates to exploration. Being the most expensive part of a seismic venture its importance is emphasized in the practical, the scientific and the cost-efficient points of view. Understanding these fundamentals of seismic field acquisition will result in better data processing and superior interpretation of the results.
