Preliminary result from pore pressure monitoring on an unstable clay slope

Engineering Geology, 2004
Abstract We monitored positive pore water pressure in a clay slope in the Apennines to investigate how rainfall influences the pore pressure distribution along the soil profile and, consequently, affects slope stability conditions. Data refers to the first season of monitoring activities (August 2001–June 2002).

An analytical model for the monitoring of pore water pressure inside embankment dams

Engineering Structures, 2018
Abstract The hydraulic behaviour of embankment dams is influenced by many factors, such as hydrostatic loads and settlement. Particularly, the delayed response due to the diffusion phenomena plays a crucial role in the interpretation of the monitoring data gathered in embankment dams.

Excess Pore Pressure Measurement and Monitoring for Offshore Instability Problems

Offshore Technology Conference, 2007
Abstract In situ pore pressure is one of the fundamental parameters required for assessing the strength and stability of geomaterials. In particular, identification of pore pressure regimes is necessary in geohazards studies. Offshore geological processes such as rapid sedimentation, minor slides, erosion, and fluid

Monitoring tool for 4D hydrological pore pressure variation

2022
We present a physics-based monitoring tool for four-dimensional pore pressure variations, using seismic ambient noise. We use passive image interferometry to retrieve surface-wave velocity changes as a function of frequency. We show that surface-wave velocity changes can directly be linked to depth variations of pore pressure change through sensitivity

Novel Apparatus and Methodology to Permanently Monitor Formation Pore Pressure in a Wellbore

Fourth EAGE Shale Workshop, 2014
We introduce a novel approach to measure directly the formation pore pressure and temperature during injection and production operations. We analyze a set of acquired data and compare with conventional injection operation data. Through a system identification algorithm, we process the raw data and remove noise from the data.
