Distributed Fiber-Optic Sensing (DFOS) comprises Distributed Acoustic Sensing (DAS), Distributed Strain Sensing (DSS), and Distributed Temperature Sensing (DTS). DFOS systems continuously measure wideband strain and/or temperature along an extended spatial and temporal range. DAS has emerged and is rapidly evolving as the technology of choice for seismic imaging and can also be used for reservoir monitoring. DSS and low-frequency DAS allow for the characterization of geomechanical processes such as hydraulic fracturing and moving pressure fronts. DTS is widely used in borehole monitoring during production. Despite the many applications and benefits of DFOS, leveraging its full power still requires tailored hardware and software development. This workshop brings together new geophysical applications of DFOS systems as well as recent developments in processing and interpretation algorithms, with topics including but not limited to:

• DAS-based seismic imaging (surface/borehole seismic)
• DFOS-based long-term reservoir and production monitoring
• Completion and hydraulic fracturing evaluation with DFOS
• DFOS applications in geothermal fields
• DFOS applications in CO2 sequestration projects
• New development of DFOS acquisition and instrumentation
• Data management, sharing, and compression of massive DAS datasets
• Machine learning and pattern recognition applications using DFOS data
