Course Description
Click here to see who has attended this course
In modern exploration for oil and gas, geophysics is a key to success, particularly in offshore and frontier areas. Contemporary geophysics (seismic) provides the necessary technology to remote-sense the target to reduce the exploration drilling risk. Seismic also plays a significant role in reservoir characterization and development.

Geologists and Engineers have learned to visualize and quantify rock properties from their physical properties graphically represented in well logs. The challenge is to become equally comfortable with seismic data. The seismic trace can be considered as an additional log which, on the one hand comes by the thousand, yet on the other, does not have the resolving power of the sonic or density log.

This three-day course presents the basic geophysical principles in a non-mathematical yet practical, tutorial fashion with numerous exercises. The course will cover data acquisition, processing and interpretation.

Who Should Attend
Petroleum Geologists, Engineers and Junior Geophysicists of any length of experience will find this course of significant benefit in understanding seismic fundamentals and will learn the advantages of seismic data in exploration and reservoir characterization.

"Carl Sagan said "Somewhere, something incredible is waiting to be known" - He should have taken this course. So much knowledge has been lost in our industry. Hearing Dr. Wren speak is a golden opportunity. Logical structure at the correct level of detail for the audience. Fantastic industry examples and history with meaningful exercises."
- Manager, Geological Optimization

"This is an excellent course that is structured well, providing a foundation early on and building toward more in-depth knowledge and applications later on. Easton is an excellent lecturer and managed to present very technical material in an engaging manner, using "real-world" analogies often. The handouts and worksheets were very effective for keeping me engaged in the content. Easton fostered a collaborative environment and encouraged questions. "
- New Grad GIT

"Great course for Geologists wanting to learn more about Geophysics and Geophysical interpretation. I liked the worksheets where we tried to interpret seismic. Enjoyed the stories too."
- GIT

"Really liked the course and enjoyed it. The real world examples helped to understand the applicability of geophysics and seismic. Easton's knowledge of the subject is unmatched. "
- Engineer

"I thought the content of the course was at a good understanding level. It was engaging and I feel I am walking away with a much better understanding of geophysics. I enjoyed how interactive the course was. I always feel this enhanced my learning especially in short courses. All the extra stories really helped my understanding of industry history as someone who just started 3 months ago!"
- GIT - Hydrogeology

"The course overall went very well! Knowledgeable instructor, very hands on and intuitive, interactive, making it easy to learn. The course was very informative, with fantastic levels of expertise and real world knowledge. Very hands on with plenty of exercises that have sprung further development and learning. The interactiveness was unparalleled. "
- Data Science EIT

"Great balance on presentation material and exercises. Wonderful background story. Great instruction with the amount of detail vs. the big picture."
- Manager of Geo Dev.

"Very well presented and laid out. Lots of interesting information particularly with background info to support. As mentioned above, good course info, great instructor and very organized."

- Geologist

"Good background to the history of seismic, what its good for, what its not, and how it was used in industry."
- Production Engineer

"Good content, covers acquisition, processing and interpretation real world examples and modelled data. Exercises were helpful putting the theory together."
- Geologist

"Very informative and so many things to learn. The material is easy to digest, contents were very interesting and the instructor is very knowledgable."
- Production Engineer

"This was a very insightful course. I learned a lot of this in school, but never applied it to the geological work I've been involved with. The timing of this course is great for me as I work closely with a geophysicist now. Its been a great refresher! I enjoyed the mix of course content, workshops and personal stories."
