Abstract

Petroleum Geochemistry is an effective tool for reducing exploration risk and Surface Geochemical Prospecting helps in search for indirect near surface hydrocarbon expressions of the deeper accumulations. KGOSN 2004/1 geochemical prospecting data is statistically evaluated and integrated with Geological horizons and fault data. Poor correlation between C1 &C2 and C3 compositions indicate plurality of origin of gases and usually biogenic gases correlate poor than the thermogenic gases. Based on C3/C1x 1000 parameter the accumulations from which the seepage occurred might be gas/ gas condensate pools. Methane anomalies integrated with faults indicated a boundary fault and faults in the area may be serving as preferential migratory path ways.
