DeepNRMS: Unsupervised Deep Learning for Noise-Robust CO2 Monitoring in Time-Lapse Seismic Images
Min Jun Park, Julio Frigerio, Bob Clapp +1
Monitoring stored CO2 in carbon capture and storage projects is crucial for ensuring safety and effectiveness. We introduce DeepNRMS, a novel noise-robust method that effectively h…
Moment tensor inversion of perforation shots using distributed acoustic sensing
Milad Bader, Robert G. Clapp, Kurt T. Nihei +1
Distributed acoustic sensing (DAS) fibers have enabled various geophysical applications in unconventional reservoirs. Combined with perforation shots, a DAS fiber can record valuab…
Low-magnitude Seismicity with a Downhole Distributed Acoustic Sensing Array -- examples from the FORGE Geothermal Experiment
Ariel Lellouch, Ryan Schultz, Nathaniel J. Lindsey +2
We show the capabilities of a downhole Distributed Acoustic Sensing (DAS) array in detecting, locating and characterizing low-magnitude earthquakes occurring in the vicinity of the…
Near-surface Characterization Using a Roadside Distributed Acoustic Sensing Array
Siyuan Yuan, Ariel Lellouch, Robert G. Clapp +1
Thanks to the broadband nature of the Distributed Acoustic Sensing (DAS) measurement, a roadside section of the Stanford DAS-2 array can record seismic signals from various sources…
City-scale dark fiber DAS measurements of infrastructure use during the COVID-19 pandemic
Nathaniel J. Lindsey, Siyuan Yuan, Ariel Lellouch +3
Throughout the recent COVID-19 pandemic when government officials around the world ordered citizens to quarantine inside their homes, real-time measurements about the use of roads,…
Approximate Bayesian inference of seismic velocity and pore pressure uncertainty with basin modeling, rock physics and imaging constraints
Anshuman Pradhan, Huy Q. Le, Nader C. Dutta +2
We present a methodology for quantifying seismic velocity and pore pressure uncertainty that incorporates information regarding the geological history of a basin, rock physics, wel…
