Abstract
Reservoirs in fractured basement are few in number and so far have contributed only a small percentage to the world production of oil and gas. Those from the fractured granite basement (FGRB) are even much fewer, and many of them were incidentally found by an unplanned exploration work. Therefore, it is not unusual to consider them as some unconventional reservoirs. But in Vietnam, where 90% of the national oil production comes from the fractured granite basement one would rather consider them as a conventional reservoir. In any case characterization of fractured granite reservoir is more difficult than that of clastic reservoirs. On top of that, experiences and literatures on this type of reservoir are not so much published and available.
In this poster a review of reservoirs in fractured granite basement is presented. The main information, including the occurrence depth, geographic locations, production, geological age etc. are summarized and tabulated. A distribution map of the studied reservoirs was digitally constructed. In particular, a more detailed description of the Fractured Granite Basment (FGB) reservoirs in Vietnam including the White Tiger field is presented.
There is no doubt that fractured granite basement reservoirs will play a more and more important role in future E&P in the region and all over the world. The paper is expected to bring a useful review that is of interest for those will be or are dealing with exploration and production of reservoirs in fractured granite basement.
Almost 30 years have passed since the first oil was produced from the fractured granite basement offshore Southern Vietnam there are still many questions left to be answered for this special type of reservoir and its fracture system characterization. In this study, we tried to investigate the contributions of micro-fracture and macro-fracture porosity by revisiting and deriving the coefficient of porosity partitioning and applying for a case study in the Cuu long basin.
