The NORMS Laboratory for Reservoir Physics hosts state-of-the-art, bespoke facilities for measuring self-potential during single- and multi-phase flow in intact rock samples at elevated temperature and pressure.
The measurements are used to determine the zeta potential and understand key mineral-surface to pore-scale mechanisms that control improved and enhanced oil recovery in controlled salinity waterflooding (CSW). They also underpin novel methods for imaging the flow of water in oil and gas reservoirs (Waterfront Imaging using Self Potential - WISP) and intrusion of saline water movement into coastal freshwater aquifers (Saline Intrusion monitoring using Self Potential - SISP).
Measurements of self-potential are supported by a range of additional experimental techniques to characterize the rock samples and electrolytes, including SEM, XRF, porosity, permeability, electrical conductivity, ion chromatography and (through facilities in the QCCSRC laboratories) micro-CT.
