Passive Seismic Tomography

Passive Seismic Tomography (PST) is an advanced geophysical imaging technique that utilizes naturally occurring seismic waves to investigate the Earth’s subsurface. Unlike active seismic methods, which require controlled sources such as explosives or vibrators, PST relies on natural seismic energy from earthquakes and microseismic activity. This makes it a non-invasive, environmentally safe, and cost-effective solution for deep exploration.

• Deployment of Seismic Network:
A dense array of highly sensitive broadband seismometers is installed across the survey area.

• Continuous Data Acquisition:
These instruments continuously record regional and teleseismic events over a period of weeks to months.

• Advanced Processing & Inversion:
Using robust tomographic inversion techniques, seismic velocity models (P-wave and S-wave) are generated.

• 3D Subsurface Imaging:
The results provide high-resolution 3D velocity models that reveal structural, lithological, and fluid-related variations in the subsurface.

Passive Seismic Tomography is a versatile method that supports a wide range of industries and research fields:

• Oil & Gas Exploration:
Mapping deep hydrocarbon reservoirs, migration pathways, and fault systems.

• Mineral Exploration:
Locating concealed mineral deposits and understanding geological controls.

• Geothermal Energy:
Identifying geothermal reservoirs, heat sources, and fluid flow systems.

• Groundwater Studies:
Characterizing aquifers and subsurface hydrological structures.

• Earthquake & Tectonic Research:
Studying crustal and lithospheric structures, seismogenic zones, and fault dynamics.

✅ Non-invasive & Environmentally Friendly: No artificial seismic sources required.

✅ Cost-effective: Long-term monitoring with minimal field disturbance.

✅ Deep Imaging Capability: Maps structures from shallow layers to lithospheric depths (tens to hundreds of kilometers).

✅ High-Resolution Models: Provides accurate 3D velocity structures for reliable interpretation.

✅ Multi-industry Applications: Suitable for energy, mining, water resources, and scientific research.
