Mobile NMR for rock porosity and permeability
… (NMR) core-scanners were used to measure porosity and permeability of water-saturated drill cores and core plugs in a non-destructive way. In addition to their use in the laboratory, the small and light-weight devices are conveniently shipped, e.g. to drilling platforms. They allow rapid …

Water borne transport of high level nuclear waste in very deep borehole disposal of high level nuclear waste
… calculated that within a borehole with a host rock porosity of 10-⁵ Darcy, it would take approximately 10⁵ years for the radionuclides to escape. As the rock porosity decreases, the escape time scale increases, and the escape fraction decreases exponentially. Due to the conservative nature of …

Inversion Analysis of Time-Domain Controlled-Source Electromagnetic Data to Characterize Offshore Freshened Groundwater in the Canterbury Bight, New Zealand, and Offshore Maltese Islands
… models with subsurface properties, such as host-rock porosity derived from in situ measurements or seismic data, enables estimates of pore-water salinity, while correlation with seismic reflection profiles allows broader geological interpretation. However, deterministic inversion approaches …

Transport and seismoelectric properties of porous permeable rock : numerical modeling and laboratory measurements
… (SE) properties of porous permeable rock. Accurate information of rock transport properties, together with pore geometry, can aid us to better quantify the frequency dependence of its SE coupling coefficient. With the development of micro-CT (pCT) scanners, microstructure of the …

An experimental investigation on Archie parameters at ambient and overburden conditions of clean reservoir rocks.
… of the effect of overburden pressure, porosity type and experimental conditions on the electrical properties (Archie's parameters) of clean reservoir rocks. The samples were from sandstone formations (North Sea), and carbonate formations (Sirte Basin, Libya). Although much work has been …
