... to model the stress dependency of P-wave velocity for rocks under differential stress. INTRODUCTION The stress dependency of elastic wave velocity of rocks is important for many geophysical applications such as pore pressure prediction and hydrocarbon detection. However, uncertainty still exists...

.... For each type, we measured the Biot effective stress coefficient, the rock matrix permeability, and the fracture permeability under various stress states, which allowed us to examine the stress-dependency of the Biot coefficient and investigate rock matrix-fracture interactions for transport of pressurized...

... measurements on three milli-Darcy cores. The nano, micro, and milli-Darcy core samples are from Niobrara outcrop, and Bakken and Middle East oil bearing carbonate reservoir cores, respectively. Our results show that, (a) stress dependency and hysteresis of permeability was observed to be inversely related...

... rock stiffness is a stress level dependent parameter in fractured rocks. This study reveals that a new physical parameter ( n ) affect the normal stiffness of fractured rocks. The stress dependent normal stiffness in fractured rocks is modeled as an empirical power law function of effective normal...

... and inexpensive. Test procedures are straightforward. The applicability and practicality of the technique are demonstrated by a long-term test conducted in a longwall panel at a coal mine. The investigation reveals the stress dependency of the deformation modulus and the Poisson's ratio of this coal. 1...
