ABSTRACT

The studies on the helium in the petroliferous tube wells in Saugor Division, southern Ganga Basin region has been carried out in great detail in 50 Tube wells, along with the stable isotopic analysis were carried out for the gas sample were collected from the 50 tube wells in Sagar and Damoh District of M.P. The discovery of the rare gas helium in hydrocarbon rich zone in the tube wells in  agricultural field at Garhakota, Rahatgarh, Bina, Banda and Sagar Tahsils, of District and Batiyagarh, Patharia, Jabera, tahsils in Damoh District  of  M.P. is a unique finding in  rocks of the Vindhyan Super Group,  in  the history of  Earth Science in India. The depth of tube wells are varying in 300 feet to 750 feet. On the basis of geochemical analysis, it is remarkable to note that  average values of helium contents varies from 0.34 % to 0.732 % along with the  72% to 99 % of methane and ethane, and minor amount of oxygen, nitrogen and CO2 gases in the hydrocarbon rich zone are recorded during the geochemical  and stable isotope  analysis. It has been found in the stable isotope δ C13 value the values for the methane is - 43.6 per mil w. r. t. to - 54.9 per mil w.r.t. PDB and for the Ethane gas is --24.9 to --26.4 per mil w. r. t. PDB in the gas samples collected in the saturated sodium chloride solution in the glass bottles at various sites in Sagar and Damoh District. The occurrence of rare helium gas in the Hydrocarbon rich zone is reported first time in Jan, 2007 from the tube wells of Sagar Distt, which were geochemically and stable isotopically analyzed in the labs of KDMIPE Dehradun and NGRI Hydrabad.  The gaseous hydrocarbon analysis show the  presence of moderate to low concentration of methane (C1) 1 to 104 ppb, Ethane (C2)-1 to 14 ppb, Propane (C3) 1 to 10 ppb, i- Butane (i C4) 1 to 9 ppb and  n  Butane (n C4) 1 to 8 ppb in the soil   samples collected from different  locations. The Result of the adsorbed soil gas and 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 are indicative that this gas is of thermogenic origin, which must have been formed at very high temperature and pressure condition in the deeper horizon of the Great Vindhyan sedimentary basin of an early Proterozoic (> 600 m.y.) period.
