National Geophysical Research Institute
Encyclopedia
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:
CSIR India
Council of Scientific and Industrial Research established in 1942, is an autonomous body and India's largest Research and Development organization, with 39 laboratories and 50 field stations or extension centers spread across the nation, with a collective staff of over 17,000...

Research areas covered by this institute include hydrocarbon
Hydrocarbon
In organic chemistry, a hydrocarbon is an organic compound consisting entirely of hydrogen and carbon. Hydrocarbons from which one hydrogen atom has been removed are functional groups, called hydrocarbyls....
and coal
Coal
Coal is a combustible black or brownish-black sedimentary rock usually occurring in rock strata in layers or veins called coal beds or coal seams. The harder forms, such as anthracite coal, can be regarded as metamorphic rock because of later exposure to elevated temperature and pressure...
exploration, mineral
Mineral
A mineral is a naturally occurring solid chemical substance formed through biogeochemical processes, having characteristic chemical composition, highly ordered atomic structure, and specific physical properties. By comparison, a rock is an aggregate of minerals and/or mineraloids and does not...
exploration, oil exploration, deep seismic sounding studies, exploration and management of groundwater
Groundwater
Groundwater is water located beneath the ground surface in soil pore spaces and in the fractures of rock formations. A unit of rock or an unconsolidated deposit is called an aquifer when it can yield a usable quantity of water. The depth at which soil pore spaces or fractures and voids in rock...
resources, earthquake
Earthquake
An earthquake is the result of a sudden release of energy in the Earth's crust that creates seismic waves. The seismicity, seismism or seismic activity of an area refers to the frequency, type and size of earthquakes experienced over a period of time...
