Abstract

A large number of oil and gas reservoirs across the world are naturally
fractured, f r om which a significant amount of hydrocarbons are produced.
Naturally fractured reservoirs, like all reservoirs, are exploited in t w o stages:
primary recovery and secondary recovery (sometimes followed by tertiary
recovery, i.e. enhanced oil recovery (EOR)), with different recovery
mechanisms. During primary production, the reservoir is produced by fluid
expansion. In secondary production and EOR, since the fractures are much
more permeable than the matrix, the injected water or EOR agent flows
rapidly through the fracture network and surrounds the matrix blocks. Oil
recovery then depends on efficient delivery of water or EOR agent to the
matrix through the fracture network.
