For fractured reservoirs with unknown fracture distributions, the characteristics of fracture distributions are crucial for determining their production behaviors.
Studies have shown that natural fractures obey fractal distribution in fractured reservoirs.

These findings are used to develop a methodology to characterize rock matrix block size distribution in fractured aquifers and to estimate dispersivity based on a tracer test, which will improve our decisions concerning the remediation of contaminated sites.
(10−7 10−5 m−1) This method for obtaining Ss values from short-interval, straddle packer tests improves the estimation of both K and Ss and provides opportunity to study their spatial distribution in fractured rock.
From a measurement of roughness height distribution of fractured surfaces using a surface profiler, the roughness-induced crack closure was evaluated as the main factor at low stress intensity factor range ΔK.
The fault zone is characterized by the heterogeneous distribution of fractured and brecciated rocks and a very limited distribution of fault gouges (Figure 3).
Based on recovered cores, there is a wide distribution of fractured rocks and drilling-induced breccia in the fault zone, while the other abovementioned structural elements show a relatively limited spatial distribution.
A flow equation similar to Eq. (20) (nonlinear parabolic differential equation) was solved numerically using implicit finite difference for non-steady steady flow, anon-steady steadyistribution in flowtured reservoirs (Yilmandethel. 1994).
The distribution of fractured bones significantly differed among the types of accidents (p < 0.001).
