Frequently Asked Questions
Near-surface geophysics involves non-invasive techniques to image and characterize the shallow subsurface for engineering, environmental, and infrastructure applications. PARSAN, a pioneer in India, applies it extensively using methods like Ground Penetrating Radar (GPR), Electrical Resistivity Imaging (ERI), Seismic Refraction, MASW, ReMi, Crosshole and Downhole Seismic, Seismic Tomography, Microgravity, Induced Polarization, and Airborne Geophysics. These techniques support dam safety, tunneling, groundwater, mining, utility detection, concrete inspection, and infrastructure development. By integrating multiple methods, PARSAN delivers cost-effective, high-resolution subsurface models that guide selective drilling, detect voids or seepage, assess bedrock, and reduce uncertainty in complex geotechnical conditions.
PARSAN delivers geophysical contracting and consulting services across diverse sectors including:
- Infrastructure: Roads, bridges, tunnels, ropeways, airport, etc.
- Energy: Hydropower, thermal, Pumped Hydro, Solar energy, Wind energy and nuclear power plants
- Water Resources: Dam safety, leakage detection, and deep aquifer mapping
- Minerals & Mining: Mineral exploration (including atomic minerals) and feasibility studies
- Environmental: Contaminated site investigations and landfill studies This wide application ensures that PARSAN remains a trusted partner for both public and private sector mega-projects in India and abroad.
PARSAN is recognized as a leader in engineering geophysics in India due to its pioneering legacy, advanced capabilities, and innovation-driven approach. Established in 2001, it was among the first private-sector companies to offer comprehensive near-surface geophysical services and today possesses the largest and most advanced suite of geophysical equipment in the country. Under the leadership of Dr. Sanjay Rana, a renowned geophysicist, who introduced several cutting-edge technologies in India- including Ground Penetrating Radar (GPR), high-resolution seismic tomography, Subsurface Utility Engineering (SUE), and Passive Seismic Tomography, company remains at forefront of innovation. A key strength lies in its highly qualified and experienced manpower, comprising multiple PhDs, M.Techs, and graduate engineers who bring deep technical knowledge and field expertise to every project. With ISO 9001:2015 certification, a global footprint, and a robust portfolio of high-impact projects across dams, tunnels, metros, mining, and groundwater, PARSAN integrates multiple geophysical techniques to deliver high-resolution, cost-effective, and client-focused subsurface solutions across India and abroad.
Yes. Beyond India, PARSAN has executed projects across Singapore, Oman, Afghanistan, Bahrain, Kuwait, Saudi Arabia, Bhutan, Bangladesh, and Nepal. We also maintain agent offices in Egypt and Sudan to support regional clients. This international presence enables us to bring global best practices and site-specific solutions to diverse geographies, from hostile terrains to highly urbanized regions.
PARSAN contributes significantly to cost and time savings in large infrastructure projects by employing advanced near-surface geophysical techniques that provide rapid, non-invasive subsurface characterization. Their methods- such as Ground Penetrating Radar (GPR), Electrical Resistivity Imaging (ERI), Seismic Refraction, MASW, and Seismic Tomography- enable early detection of geological anomalies, voids, fractures, and utilities without the need for extensive drilling. This targeted approach allows project planners to optimize borehole locations, reduce unnecessary excavation, and mitigate risks before construction begins. By integrating multiple geophysical methods, PARSAN delivers high-resolution, volumetric subsurface data quickly, helping clients make informed decisions, avoid costly delays, and accelerate project timelines.
