Abstract

Studies on the geophysical exploration of the Helium gas in the rocks of the Vindhyan Super Group around Sagar, South Ganga Basin, Bundel khand  region, M.P. is carried out in the detail with joint collaboration of Dept. of Applied Geology and ONGC Energy Centre, Ahmadabad. As Author has already reported the Discovery of Helium has leakages through   more than 50 tube wells/e wells excavated in agriculture fields various Villages in Sagar Distt. The geochemical analysis of the soil, gas and water indicates remarkable amount of Helium gas in these tube wells, containing about 0.45 to 0.735 and methane varying from 72 % to 99%. These investigations were done in the long research work ( more than 25 years)dedication carried out in this area and research finding published in the Journal of National  and International repute, which has attracted the officers/ Scientists of ONGC, Dehradun, CGWB, Faridbad, Atomic Mineral Directorate Hyderabad and Bhabha Atomic Research Centre Mumbai.
The Result of  the stable isotopic analysis of Ethane gas in these  samples δ C¹³   value are ranging from -24.9 per mill w.r.t. PDB and -26.9 per mill w.r.t. PDB and the Methane gas are ranging from   Isotopic Values -54.0-
per mill w.r.t. PDB  to -61.5 per mill w.r.t. PDB are indicative that this gas is of thermogenic origin, which must have been formed at very high temperature & pressure condition in the deeper horizon of the great Vindhyan sedimentary basin of  late   Proterozoic (>500m.y.) period. A reporting of leakages of above mentioned gas from 50 tubewells in the inliers of Vindhyan rocks and even in the Deccan trap rocks ensures that this area must be having a big gas reservoir within Vindhayn rocks around Sagar- Distt. in M.P.                                                             
  The ONGC energy Centre Ahmadabad has started the detail collaborative geophysical work on the drilling exploration upto the depth of 600 m has been carried out and to be carried out in various location from where the leakages of has been earlier reported earlier.  In these 600 m deep  drill holes detail geophysical logging including the gamma ray logging and Neutron logging, lithological an d structural logging will be carried out to know the probable gas reserve and at what depth the, we can get the gas for the exploration  and utilization of these uses for industrial purpose and other uses etc .
 The detail geophysical studies will be very much helpful in the gas reserve calculation and the depth of the gas pockes in the South Ganga Basin in Bundelkhand region in M.P.
