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.

We plan to have a few invited talks and welcome abstracts related to DFOS, including but not limited to the following topics:

● 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 and CO2 sequestration projects
● Data management, sharing, and compression of massive DAS datasets
● Machine learning and pattern recognition applications using DFOS data
● New development of DFOS acquisition and instrumentation

The technical sections on DAS primarily focus on DAS-based seismic methods, with very few applications of distributed temperature sensing (DTS) and distributed strain sensing (DSS). Additionally, in our workshop, we intend to place greater emphasis on non-VSP and emerging applications, including urban, near-surface, and energy-transition related topics. The field of distributed fiber-optic sensing is rapidly evolving. A workshop is necessary to capture more recent developments than the technical sections.
