The National Geophysical Research Institute (NGRI) is a geoscientific research organization established under CSIR India in Hyderabad, India in 1961. It is supported by over 200 scientists and other technical staff whose research activities are published in several journals of national and international interest.

Research arenas covered by this institute include hydrocarbon and coal exploration, mineral exploration, exploration and management of groundwater resources, earthquake hazard assessment, structure of earth's interior and its evolution, and geophysical instrument development.

The major areas where research has been carried out are:
  • Hydrocarbons
  • Minerals
  • Groundwater
  • Eathquake hazard
  • Lithosphere
  • Environmental Geophysics

The following are the projects succesfully carried out in NGRI by the eminent researchers and scientists:

  • Study of satellite and land gravity and magnetic (G-M) data for understanding the geodynamics of the Indian lithosphere and exploration of natural resources
  • Study of Mesozoic sediments for hydrocarbon exploration in central india
    Application of magneto-tellurics to natural resources exploration and lithospheric studies
  • Deep resistivity sounding (DRS) and Controlled source audio magneto-telluric (CSAMT) studies for upper crustal structure
  • Exploration of gas-hydrates along Indian continental margins
    Electrical and electromagnetic (EM) field and physical modelling for shallow sub-surface studies
  • Petrology, geochemistry of the mafic-ultramafic and alkaline rocks of Dharwar Craton; Bundelkhand; Central India and Deccan flood basalt province and mineralization through space and time
  • High-resolution multi-parameter airborne geophysical surveys for mineral, oil & groundwater exploration and development of interpretational techniques for airborne data
  • 2D/3D Seismic studies in various coal basins of India, site characterization and shallow geophysical studies for mineral exploration, engineering and archaeological projects.
  • Groundwater management in hard rock aquifers including resources augmentaion and protection from geochemical contamination
  • Quaternary geo-chronological studies (paleo-seismology / paleo-tsunami, paleo-climatology and exhumation) in the NE India and Andaman Islands
