... on stress-strain relationships, proposed tests were conducted by varying the length/width ratio of the prismatic Berea sandstone specimens from 1 - 2.5. The results demonstrated that the more smooth stress-strain relationship, the shorter specimen length. On the other hand, the longer specimens showed more...

... ABSTRACT: The feasibility of geologic hydrogen (H 2 ) storage in saline aquifers necessitates a thorough analysis of multiphase fluid flow and fluid distribution. This study investigates Berea sandstone as a proxy for hydrogen injection into porous rock. An experimental setup has been...

.... In this study, we developed a first-of-its kind triaxial cell that allows one to apply electrical current, with temperature and pore pressure data collected during the joule heating process of a Berea Sandstone rock specimen. We investigated the relationships between pore fluid composition, pore pressure...

... measurements and observations to understand these important processes, we study laboratory acoustic emissions in combination with numerical models to shed light on the physics governing seismicity. A dry sample of Berea sandstone was tested to failure under a confining pressure of 40 MPa in a triaxial machine...
