The work of the Rock Physics Laboratory is supported by 2 members of full time academic staff and a technician. We currently host 2 PhD students.
Alumni from the lab can be found in academia, government, and key industries worldwide.
The NOC Rock Physics Laboratory (RPL) specialises in experimental studies of geophysical phenomena in marine sediments and rocks. Research undertaken in the laboratory aims to further the understanding of fundamental interactions between sediment/rock properties and their elastic and electrical properties.
50mm diameter core plug rigs: We operate four 50mm diameter core plug high pressure (max. 60MPa) testing rigs, instrumented for measuing frequency-dependent P- and S-wave velocity and attenuation (0.1–1.0 MHz), Electrical Resistivity Tomography (ERT) and Electrical Resistivity Anisotropy (ERA). The rigs are temperature controlled (−10°C to 50°C) and can inject a range of pore fluids (air, water, brine, oil, methane, CO2 and mixed phase). The rigs can also measure sample strain and in situ absolute and relative permeability using various steady state and transient methods.
70mm diameter impedance tube: The impedance tube can accurately measure P-wave velocity and attenuation over the frequency range of many sonic logging tools (1–10 kHz). The 5m long impedance tube can accommodate 70mm diameter samples of hard or soft sediment up to 1m in length. The impedance tube is also instrumented with our ERT and ERA systems and is temperature (0–50°C) and pressure controlled (0–60MPa) enabling a wide variety of experiments to be performed, e.g., gas hydrate and carbon capture and storage (CCS) studies.
