Fault zone fabric and fault weakness
Nature, 2009Geological and geophysical evidence suggests that some crustal faults are weak compared to laboratory measurements of frictional strength. Explanations for fault weakness include the presence of weak minerals, high fluid pressures within the fault core and dynamic processes such as normal stress reduction, acoustic fluidization or extreme weakening at ...

Journal of Structural Geology, 1987
Abstract Many tectonic faults and tension fractures are, at least initially, composed of separate segments. This note deals with a little explored reason for this phenomenon which, in faulting, has obvious implications both for the migration of hydrocarbons and for the sealing capacity of faults. Theoretical arguments based on CoulombMohr's theory of

Granular Packings and Fault Zones
Physical Review Letters, 2000The failure of a two-dimensional packing of elastic grains is analyzed using a numerical model. The packing fails through formation of shear bands or faults. During failure there is a separation of the system into two grain-packing states. In a shear band, local "rotating bearings" are spontaneously formed.

Facies Modelling in Fault Zones
ECMOR X - 10th European Conference on the Mathematics of Oil Recovery, 2006Traditionally fault impact on fluid flow is included by assigning transmissibility multipliers to flow simulation grid cell faces co-located with the fault plane (Manzocchi et al. 1999). A new method, called Fault Facies modelling (Tveranger et al. 2004, 2005), captures fault impact by considering faults as deformed rock volumes rather than simple ...

Flow Through Inhomogeneous Fault Zones
Proceedings of SPE Annual Technical Conference and Exhibition, 2007Abstract Faults significantly influence fluid flow in reservoirs. In standard reservoir flow-simulator grids, faults are represented as surfaces or planes. However, outcrop studies show that faults often must be regarded as volumetric elements.
