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

Research areas covered by this institute include hydrocarbon and coal exploration, mineral exploration, oil exploration, deep seismic sounding studies, exploration and management of groundwater resources, earthquake hazard assessment, structure of earth's interior and its evolution (theoretical studies), and geophysical instrument development.

The major facilities available at "NGRI" include:

• Mineral Physics Laboratory with high-pressure Diamond Anvil Cell (DAC), ultra high resolution (0.02/cm) double monochorometer, and micro-Raman spectrometer.
• High-pressure laboratory consisting of Keithly electrometer, strain-measuring sensors, universal testing machine (100 tons), and Bridgeman-Birch high-pressure apparatus.
• In-situ stress measurement facility consisting of hydraulic equipment.
• Rock magnetism laboratory consisting of astatic magnetometer, digital spinner magnetometer, alternating magnetic field and thermal demagnetizers, high-field and low-field hysteresis and susceptibility meter.
• Geochemical laboratory consisting of fully automated X-ray Fluorescence Spectrometer (XRF), Atomic Absorption Spectrometer, Inductively Coupled Plasma Mass Spectrometer (ICPMS), and Electron Probe Micro Analyzer (EPMA).
• Geochronology and isotope geochemistry laboratory with facilities for Rb-Sr, Sm-Nd, and Pb-Pb analyses.
• EM, Resistivity, and IP Model Laboratories.
• Continuous Flow Isotope Ratio Mass Spectrometer Laboratory (CFIRMS).
• Helium Emanometry, Heatflow and Radiometry Laboratory.
• Tritium and carbon dating laboratory for groundwater.
• Centralized computing facilities: PC-LAN and an array of Sun Workstations.
