HYDROCARBON GASEOUS ANOMOLIES FOUND IN AGRICULTURE FIELD AROUND SAGAR Distt., SOUTHERN FRINGES OF BUNDELKHAND REGION, MADHYA PRADESH. INDIA.

Abstract

The gaseous anomalies has been recorded in the Agriculture filed in Sagar Distt. of M.P.. The
discovery of the rare gas helium in hydrocarbon rich zone in the tube wells in agricultural field
of Pipariya - Bhutoli Garhakota Tahsil and Meerkheri and Rahatgarh town in Rahatgarh tahsil
of Sagar District in M.P., is a unique finding in the history of Earth Science in India. It is
remarkable to note that 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
Rahatgarh, Meerkheri, Piparia, Bhutoli villages in Sagar District. The occurrence of rare helium
gas in the Hydrocarbon rich zone is reported first time in Jan, 2007 from the tubewells of Sagar
Distt, which were geochemically and stable isotopically analyzed at KDMIPE Dehradun &
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 nButane ( 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
C
13 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 early
Proterozoic (>500m.y.) period.
