Pore-Pressure Sensors and Multi-packer

Pore pressure refers to the pressure of groundwater held within a soil or rock, in gaps between particles (pores). To measure pore pressure in different intervals of the experiment volume, we installed a multi-packer that separates the monitoring borehole "MB2" into several segments, each coming with one pressure sensor. Our multi-packer comes with 7 intervals separated by packers of 1m length. The intervals were chosen based on the observed fracture/fault clusters from the core and logging observations.
