TLDR
In this paper, the authors measured the permeability of the Berea Sandstone as a function of both confining pressure and pore pressure and found that the pore fluid has a higher compressibility than the granular framework which supports externally applied stresses.Abstract:
Permeability of the Berea Sandstone was measured as a function of both confining pressure and pore pressure. As expected, permeability decreased with increased confining pressure and increased with increasing pore pressure. However, pore pressure had a significantly larger effect on permeability than did confining pressure. This behavior can be explained if the matrix through which the pore fluid flows has a higher compressibility than the granular framework which supports externally applied stresses.read more

Limits on lithospheric stress imposed by laboratory experiments
W. F. Brace,David L. Kohlstedt +1 more
TL;DR: Byerlee's law, converted to maximum or minimum stress, is a good upper or lower bound to observed in situ stresses to 5 km, for pore pressure hydrostatic or subhydrostatic as discussed by the authors.

Permeability of crystalline and argillaceous rocks
TL;DR: In this article, the authors compared laboratory, in situ, and inferred values of permeability, k, of crystalline and argillaceous rocks, and found that in situ k ranged from about 1 μd (10−14 cm2) to 100 md; this is close to the permeability of many sandstones and about 103 times greater than laboratory measurements for intact crystalline rocks.

Permeability of fault-related rocks, and implications for hydraulic structure of fault zones
TL;DR: In this article, the authors investigated the permeability structure of a fault zone in granitic rocks by laboratory testing of intact core samples from the unfaulted protolith and the two principal fault zone components; the fault core and damaged zone.

Laboratory measurement of compaction-induced permeability change in porous rocks: Implications for the generation and maintenance of pore pressure excess in the crust
TL;DR: In this paper, the dependence of pore pressure and porosity on the pore structure and its compressibility has been investigated experimentally in five sandstones with porosities ranging from 14% to 35%.

Internal structure and permeability of major strike-slip fault zones: the Median Tectonic Line in Mie Prefecture, Southwest Japan
TL;DR: Fault permeability data from the Median Tectonic Line (MTL) in Mie Prefecture, Southwest Japan suggest that fault permeability models are currently too simplistic for such large structurally complex fault zones.

Permeability of granite under high pressure
TL;DR: In this article, the authors measured the porosity of Westerly granite as a function of effective pressure to 4 kb and found that porosity is correlated with the electrical resistivity of the granite.
