Abstract :
A large percentage of the world’s oil and natural gas is contained in rocks, such as carbonates, in which it is often difficult to extract fluids unless the rocks contain natural or induced fractures . Natural fractures and faults are the primary pathways for hydrocarbon migration and production in many reservoirs. A fractured reservoir have a significant effect on reservoir fluid flow in the form of increased reservoir permeability, increased porosity, and increased permeability anisotropy . In this article investigated some effective parameters that have special influence in fractured reservoir , for instance total stock tank oil produced by gas influx .
