The oil cracked gas has been identified in Kekeya region based on the geochemica l characteristics of oil and gas. Overall, integrated analysis results show that the oil and gas are in the stage of high maturity that oil cracking occurs. Bes ides, the abundant diamondoid hydrocarbon and absent of pyrrolic nitrogen compou nds in associated crude oils are very similar to the characteristics of associat ed oil for oil cracked gas reported in the other region. Moreover, the methane content increased as the depth of formation, etc. All these result shows that oil cracking is very important process for the generation of natural gas in this region.
Key words: Kekeya; Oil cracked gas; Natural gas; Diamondoid hydrocarbon.
