Geochemistry of Oil Fields, East Java Basin: Biomarker Characterisation

Abstract

Biomarkers are molecular fossils derived from living organisms and these complex compounds are composed of carbon, hydrogen and other elements. Biomarkers show little or no change in chemical structure from their parent organic molecules in living organisms [1]. Biomarkers are very useful due to their complex structures, revealing precise information about the depositional origins. It has been recognized that biomarkers in oils and rock extracts reflect depositional environment [1-3]. Therefore, biomarkers are used to achieve the objectives in such study to know the characterization of oil samples.
