Real-time In-situ Seismic Imaging: Overview and Case Study



Real-time In-situ Seismic Imaging (RISI) is a breakthrough technology for monitoring and mapping the subsurface geophysical structures and dynamics in realtime. Instead of collecting data to a central place for post-processing, the distributed seismic data processing and computing are performed in-situ, delivering an evolving 3D image in real-time for visualization. As a paradigm-shifting approach, the RISI system is plug-nplay, scalable, self-adaptive and fault-tolerant. We have created multiple in-situ distributed seismic imaging algorithms including tomography and migration, and validated them using synthetic and field seismic data sets. This paper presents a case study of travel-time seismic tomography. The RISI prototype system has been implemented, and can be extended as a general field instrumentation platform, to incorporate new geophysical data processing and computing algorithms.
