Title : Studies on the dating of natural gas in tubewells in Vindhyan rocks, Sagar-Damoh district, South Ganga Basin, Madhya Pradesh, India

Abstract:

The dating of natural gases 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 in the various Tahsils of Sagar District and Damoh District of M.P. in the south ganga basin in rocks of the Vindhyan Super Group. 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 the72% to 99 % of methane and ethane, and minor amount of oxygen, nitrogen and CO2 gases in the hydrocarbon rich zone are recorded.The 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. 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 & NGRI Hydrabad. The gaseous hydrocarbon analysis shows 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 dating & 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 & pressure condition in the deeper horizon of the Great Vindhyan sedimentary basin of an early Proterozoic (> 600 m.y.) period.
