Broadband Dielectric Analysis of Clays: Impact of Cation Exchange Capacity, Water Content, and Porosity

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 3, March 2026.
Abstract Clay‐rich soils and sediments are key components of near‐surface systems, influencing water retention, ion exchange, and structural stability. Their complex dielectric response under moist conditions arises from surface–ion electrostatics and diffuse double layers that govern transport and retention processes. This study explores the broadband

Geophysical investigation of the Pb-Zn deposit of Lontzen-Poppelsberg, Belgium [PDF]

, 2018
The drillhole information from the Lontzen-Poppelsberg site has demonstrated three orebodies and has allowed the estimation of the extension of the lodes, their dip, and the location at the ground surface.

Petrophysical Analysis of Low-Contrast Oil Reservoirs with Low Porosity and Low Formation-Water Salinity in SaPu Intercalation of Longxi Area, Daqing Oilfield, China

Applied Sciences
Low-contrast oil reservoirs have a complicated origin story that frequently results from the interaction of several different factors. The low-contrast oil reservoirs in the Daqing Oilfield’s SaPu intercalation in the Longxi Region are the main subjects ...

Estimation of the fracture density in reservoir rock using regression analysis of the petrophysical data

Geodesy and Cartography, 2016
Image logs are presently the main specialized tools for fracture detection in hydrocarbon reservoirs. Where image logs are not available, other less rewarding substitutes such as isolated well tests and type curve analysis, drilling mud loss history ...
