Real-time In-situ Seismic Imaging

Real-time In-situ Seismic Imaging (RISI) is a breakthrough technology for monitoring and mapping the subsurface geophysical structures and dynamics in real-time. A RISI system is a wireless seismic network that senses and processes seismic signals, and computes 3D undersurface structures in-situ in real-time. Instead of collecting data to a central place for post-processing, the distributed seismic data processing and tomographic computing are performed in the in-situ network and the evolving 3D image is computed and delivered in real-time for visualization.

The RISI system, as a surface seismic monitoring and imaging system, can detect the naturally occurring, low-energy seismic noise emitted from oil/gas exploration and production activities, such as wastewater injection, CO2 sequestration, hydraulic fracturing stimulation, and provide real-time awareness (in less than a second) of E&P operations.
