Geochemical Evidence for a Complex Filling History of the Agogo Structure, Papua, New Guinea

Reservoir geochemistry is a powerful tool which has been used for a variety of oil industry value-added applications. These include helping determine reservoir continuity, delineating filling histories, production allocation, predicting oil properties from side-wall core extracts, and troubleshooting packer and cement problems. Reservoir geochemistry, including GC, isotopic and biomarker analyses, of oils from the Agogo Structure, Agogo 1-X well, PNG, provides a particularly interesting example of the type of information which can be obtained. Although initial reservoir pressure data suggested vertical continuity, oils from different levels within the structure are geochemically distinct, in fact they are not even from the same source rocks. This talk will present our interpretation of reservoir continuity and filling history of the Agogo Structure based on engineering, geological and geochemical data. In addition, we will describe petroleum systems operative within this region recognized as a result of this reservoir study. [Pending Company Approval]
