【 摘 要 】

The presence of oil seepage in Central Java indicates that there is an effective petroleum system. The problem is where the oil was derived from. Biomarker characteristic is used to provide information on source rock organic matter input, depositional environment and correlation between source rock and oil seepage. The method used for this study is GC and GCMS analyses of the rock extract and oil seepage. The biomarker characteristic suggests that oil seepage in Banjarnegara is derived from the Totogan Formation, while that in Bayat is derived from the Wungkal Formation. Oil seepage in Cipluk area is deposited in the estuarine environment. Therefore, it cannot be correlated with the Kerek Formation. Oil seepage in Kedungjati and Bantal area is not derived from the Kerek and Pelang Formation.
