SISPROBE uses the passive seismic technique and offers a full range of solutions to challenges in seismic survey design, data acquisition, processing, and interpretation, as applied to petroleum and mineral exploration, geothermal energy, and geotechnical engineering. • State-of-the-art source-free, cable-free, multi-component 3D seismic imaging with global applications. Fast, cheap, and efficient, it produces accurate results using naturally occurring ambient seismicity in the earth. • Especially valuable in frontier exploration, in fold-thrust belts with complex and steep structures, for surface volcanic, shallow carbonates, shallow estuary, and transition zone-marine settings. • Smart survey planning and de-risking before high-cost 2D and 3D seismic work programs. Static surveys and long-term monitoring.
