... present results from CT imaging and mineralogical investigations of an Opalinus Clay core on different scales and different regions of interest, emphasizing especially the 3D evaluation and distribution of cracks and fractures and their impact upon mechanical testing of such material. Enhanced knowledge...

... integrity evaluation for future CO 2 storage sites in the North Sea. In this work the first results from the core opening, initial logging, material characterization and mechanical testing for parts of the core are presented. Our results indicate very low permeable shale with small pore throats ensuring...

... ABSTRACT: In preparation for well stimulation activities and the development of an enhanced geothermal system (EGS) in the Desert Peak geothermal field, a series of petrologic and rock mechanical tests were conducted on selected core samples to represent the planned stimulation interval within...

... geomaterials, sand production prevention, subsidence evaluation, compaction measurement of sedimentary basins and mechanical testing of side wall cores. 1 INTRODUCTION The geomechanical characterization of loose materials, hard soils, compacted sands, or unconsolidated shales is nowadays a very critical...
