  1. Studies for Nuclear Power Plant sites:
  2. A major concern while setting up a Nuclear Power Plant is the presence of active/capable faults in the vicinity of the site. An active/capable fault is the one which can generate an earthquake in which elastic strain that has gradually accumulated across a fault is suddenly released driving motion on the fault. The motion may last for several seconds to few minutes generating both strong ground motion and the static deformation of the ground which decreases gradually away from the fault on either side. In case the fault ruptures the surface, then static displacements are discontinuous across the fault at the ground surface, constituting a primary seismic hazard. The other important factor in assessing the seismic hazard is the amplification of strong ground motion caused due distant seismic sources, especially in lower frequencies. Thus, while conducting investigations for NPP, it is important to evaluate the seismic hazard at different scales.

  3. Site characterization studies in central Indian province for earthquake hazard assessment:
  4. The characteristics of seismic waves generated and propagated through different geological formations during the earth quakes will be dependent on local site conditions. It is evident from the past history that the damage due to earth quakes is very high in the regions with thick alluvial cover. Most of such damage is attributed to the amplification of certain frequencies in the near surface alluvium cover during the propagation of waves. The shear wave velocity of the top soils has become an important tool to estimate the frequencies and amplifications during ground motion.In central India, areas are selected to assess the seismicity and geotechnical characteristics of the subsurface in and around Lucknow, Kanpur and Allahabad.

  5. 2D/3D High Resolution Seismic Studies:
  6. Coal Bed Methane (CBM) is a natural gas produced from the coal seams. Coal Bed Methane is a mixture of hydrocarbons, dominantly methane with other minor amount of other gases like carbon dioxide and nitrogen. The amount of methane held in coal seam depends on the age, moisture content and depth of the coal. High rank coals buried at great depths (>300-1200m) are suitable for the exploitation of coal bed methane (CBM). The shallower nature of the investigations require high resolution seismic profiling in which the seismic wave is rich in high frequencies and the recording system is designed to retain as much of the high frequency reflections as possible. Identification of faults, thickness and depth of coal seams are very much essential in CBM exploration as these factors are responsible for the formation of Methane. In this technique the property of acoustic impedance is of much importance in identifying different rock formations, which are associated with coal, and it has been successfully implemented.
    3D seismic studies to map coal horizons and to delineate the associated structural features at Belphar area, Jharsuguda , Orissa sponsored by CMPDI. As a part 3D seismic study program, 10Sq. Km area was selected for identification of coal beds up to a depth of 1.5 km near Belpahar, Jahrsuguda,Orissa. Data acquisition work is in progress.

  7. Geotechnical studies near Nuclear Power plant (NPP) site, Gorakpur, Haryana sponsored by NPCIL.
  8. Geophysical Well Logging Studies at Koyna-Warna region sponsored by MoES.
  9. Seismic studies along pipe line route for Reliance.
  10. Magneto telluric studies in Eastern Ghat Mobile Belt, Eastern Dharwar Craton and Cuddapa basin: INDEX Project

The objective of the MT studies is to image electrical conductivity structure of segments of the Indian lithosphere. Available MT data and new data will be used to achieve this objective. New MT data will be obtained in SISR and Himalayan regions. The data will be processed using robust codes and modeling will be done using 2D, 3D and anisotropy schemes. The obtained structure will be interpreted in terms of causative geological structures.

Magnetotelluric data collected along a 350 km profile from Chamarajnagar to Hirekerur. MT data at 34 stations are being processed and impedance values are obtained. Preliminary models show extension of conductors associated with Chitradurga Shearzone up to Moho depths.
