Porosity partitioning of a fractured granite basement (FGB) reservoir in the Cuu Long Basin, offshore Southern Vietnam

Abstract

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.
