For some decades, fractured oil/gas reservoirs, fractured aquifers
and geothermal wells have provided important resources for many countries.
Recently, fractured systems have also been under investigation
for their suitability as storage/disposal sites for
high-level nuclear waste. In this connection,
understanding and characterizing flow and transport processes in
fractured systems is a topic of major interest.
The use of the discrete modeling approach in order to study flow and
transport process in fractured systems requires the discrete description
of the fracture structure in space, which can be achieved by the help of
a fracture generator.
Within this research work, the integration of the geostatistical approach
into an existing fracture generator FRAC3D is carried out. Subsequently,
the generated systems from a newly-developted geostatistical and
an existing stochastic approach are compared and interpreted.
Furthermore, the generated system is used as a preproccesing step
for numerical simulations in order to achieve and complete the description of
flow and transport processes in fractured systems.
