217: Advancing Subsurface Knowledge Through Microseismic Insights (Joël Le Calvez)

"The value is not in the measurement per se. It is in the ability to integrate this measurement with everything else that we have access to."

Dr. Joël Le Calvez discusses January's special section in The Leading Edge on microseismic monitoring.

Joël shares how recent technological advancements and pressing societal concerns, like climate change and sustainability, are pushing microseismic monitoring to the forefront of geophysical research.

This conversation explores the complexities of integrating microseismic data with other geophysical and geologic information. Joël discusses the intricacies and challenges of detecting microseismic activity and how monitoring these events is critical for ensuring the safe operation of projects like carbon capture and storage and geothermal energy production.

Listeners will gain insights into the role of survey design in managing data volume and the importance of communication between scientists and management and among scientists themselves. This episode will help you reflect on the next frontier in microseismic monitoring and how it will shape our understanding of the subsurface.

OVERVIEW

> The rising importance of microseismic monitoring in the context of climate change and sustainability

BIOGRAPHY

Joël Le Calvez is the Principal Geologist at Schlumberger. He actively participates in the development of the processing, visualization, and interpretation software Schlumberger currently uses in relation to the monitoring of induced microseismicity coupled to hydraulic fracture treatment and other applications (e.g., CO2 sequestration, geothermal injection, etc.) using downhole, shallow wellbores and surface arrays. Before joining Schlumberger, Joël worked for the Bureau of Economic Geology at the Applied Geodynamics Laboratory and Etudes et Recherches Géotechniques. Joël was awarded a Ph.D. in salt tectonics, a M.Sc. in geosciences, and a B.Sc. in physics.
