Episode 158: What geophysicists and engineers need to know about DAS

Mark Willis discusses his upcoming Distinguished Instructor Short Course, "Distributed acoustic sensing for seismic measurements – what geophysicists and engineers need to know." In this conversation with host Andrew Geary, Mark helps geoscientists and engineers build intuition and understanding of DAS seismic technology's value, limitations, and applications. Mark also discusses the most common objection to DAS, when DAS is better than conventional seismic acquisition, and tips for someone planning their first DAS seismic survey. Mark will be teaching this course for the first time at IMAGE, and this is a great preview of the valuable, insightful, and helpful tools and resources you will gain from this course.

Episode 152: How and why DAS succeeds

Ariel Lellouch discusses his upcoming Middle East and Africa Honorary Lecture, "Applications of fiber-optic sensing to borehole seismology." In this conversation with host Andrew Geary, Ariel makes a case for geophysicists to utilize Distributed Acoustic Sensing (DAS) data in their work and why it's essential to look at data without any pre-made ideas. He also outlines the significant benefits of vertical DAS arrays and how to know when to use vertical or horizontal DAS. This is an excellent primer on DAS and a convincing case for why every geophysicist would benefit from engaging with this technology.

Episode 95: Cutting edge methods to utilize distributed acoustic sensing

In this episode, host Andrew Geary speaks with Ariel Lellouch and Tieyuan Zhu on distributed acoustic sensing (DAS), the featured special section in November's The Leading Edge.

Ariel and Tieyuan highlight new developments in algorithms impacting microseismic, new findings for hydraulic fracturing, and discuss their disagreement for the current rate the geophysics industry is adopting and utilizing DAS. This is an exciting conversation on technology that has a wide range of applications for geophysics. Hear the latest in research in 20 minutes!
