The effect of cracks on the compressibility of rock

JB Walsh - Journal of geophysical research, 1965 - Wiley Online Library
Compressibility of porous material is greater than that of solid material of the same composition,
and the difference is shown to be equal to rate of change of porosity with pressure, for …

Permeability of granite under high pressure

WF Brace, JB Walsh, WT Frangos - Journal of Geophysical …, 1968 - Wiley Online Library
The permeability of Westerly granite was measured as a function of effective pressure to 4
kb. A transient method was used, in which the decay of a small incremental change of …
