Seismic interpretation makes it possible to extract subsurface geologic information from 2 and 3 dimensional seismic data sets. It is a key enabler of many exploration but also reservoir characterisation activities. This course is designed to provide an introduction to seismic interpretation as it is applied in the industry. The course provides an understanding of the fundamentals of modern seismic acquisition and processing steps needed to prepare seismic interpretation databases. Seismic interpretation techniques in various structural and stratigraphic settings will be discussed, using a large number of examples and hands-on paper interpretation. One focus will be to link seismic information, which is usually in time domain, to the depth domain. Another objective will be to learn about seismic attributes and how to incorporate these in advanced interpretation. Finally, not all seismic features are related to geology, hence a critical task covered will be to distinguish useful data from artefacts.
Course Level: Foundation Instructor: Wilfried Gruber
Designed for you, if you are...
A geologist, geophysicist or petroleum engineer seeking to gain an understanding and practical knowledge in the seismic interpretation process
This course provides a thorough introduction and covers all aspects, from the basis of the seismic method right through to the application of seismic attributes.
How we build your confidence
Hands-on practical examples are the main focus in order for you to gain interpretation skills.
At the same time basics required to separate useful features from artefacts are communicated.
You will learn how to link well data and seismic information, correlate 2D lines, identify horizons and faults and select basic rock properties to transfer results from time to depth domain. Relationships between paper mapping exercises and workstation practices will be demonstrated.
The benefits from attending
At the end of the course you will have a good understanding of the possibilities, potential outcomes but also pitfalls and limitations of seismic data. With that foundation you will feel confident to:
Better comprehend the potential of seismic data in terms of interpretation value
