Module Fractured reservoir Petrophysics(FRP) helps users to interpret wireline data of fractured massive reservoir. The reservoir contains various rock types which are characterized by different mineral compositions. These mineral compositions have various influences on measured physical parameters, coupling with complex pore space structure such as Fracture-Open Vug-Isolated Vug system making conventional approach become incompatible. In a Fracture-Vug massive reservoir, the pore space model can be characterized as below:
• The macro-fracture system: mainly formed by tectonic activities. It includes faults, faults-related fracture usually enhanced by hydrothermal activity. Macro-fracture zones generate oil flows into wellbore, as well as accept injecting water. The permeability of macro-fracture zones can vary greatly from some mD to ten thousand of mD.
• The micro-fracture system is formed by tectonic activities and also magma shrinking. It occurs as either as an associated feature (parallel, beside) of macro- fracture zones or develops in among them without any preferred orientation. The micro-fracture system is characterized by capillary permeability.
• The open vug system that develops along the macro-fracture surfaces. Such system has been formed through a process of hydrothermal activities. It usually contributes significantly to accumulation ability and hydrodynamic permeability of the solid rock.
• The solid mass is the primary, non-destroyed magma/tight carbonate… without any fluid permeability and any accumulation ability.
• Isolated vugs (non-connected vugs) are formed either at the same time with magma cooling or in diagenesis. They do not contribute to storage capacity and permeability ability.
