Permeability is one of the most important parameters for characterizing fluid flow and production from reservoirs. In this paper, a modified pressure-pulse decay (PPD) method is proposed and tested for permeability measurement of tight cores. For this modified method, only one gas chamber is applied at one end of the test core sample, while the other end of the core is sealed. A small pressure pulse...
A hyperbolic flow rule describing the relationship between the inclination of the strain path and the stress ratio during creep was proposed based on triaxial creep experiments on two different rockfill materials. The flow rule was then incorporated into Bauer's hypoplastic model together with a new density factor which controls the magnitude of creep strain. The refined model was verified by reproducing...
