This paper focuses on the effect of water saturation on A. C. electrical conductivity and dielectric constant of fully and partially saturated hematitic sandstone sample (Aswan area, Egypt). The satu...
Geological sequestration (GS) of carbon dioxide (CO2) is considered as one of the most promising technologies to reduce the amount of anthropogenic CO2 emission in the atmosphere. To ensure success of...
Stress dependent rock physics models are being used more routinely to link mechanical deformation and stress perturbations to changes in seismic velocities and seismic anisotropy. In this paper, we in...
With advent of servo-controlled stiff testing machines, it is now possible to conduct tests on a rock in the laboratory under different variable controlled conditions. In this paper, cyclic fatigue be...
The distribution of porosity data collected at the Kloštar field is analysed. This field is located in the north-western part of the Sava depression, and represents one of the most long-standing ...
The elastic response of many rocks to quasistatic stress changes is highly nonlinear and hysteretic, displaying discrete memory. Rocks also display unusual nonlinear response to dynamic stress changes...
During the last decades several wells giving yields up to 100,000 llh have been drilled in the reddish Brumunddal Sandstone, which covers an area of approximately 10 km2 near lake Mjosa, Southern No...
The storage coefficient for a confined aquifer in lower Cambrian sandstone has been calculated, partly from pumping tests and partly from correlations of water-level fluctuations with changes in atm...

The Tonganoxie Sandstone Member (Stranger Formation) records part of the infill of an estuarine valley system that was incised during a late Missourian (Late Carboniferous) drop in sea level and subse...
Integration of ichnologic, sedimentologic, and stratigraphic studies of cores from Lower Pennsylvanian oil and gas reservoirs (lower Morrow Sandstone, southwest Kansas) allows researchers to distingui...
Compartmentalisation, the subdivision of an aquifer into discrete and relatively isolated units, may be of critical importance for the protection of groundwater although it has been largely ignored i...
Abstract: Illitization of smectite during progressive burial diagenesis occurs differently in sandstone and mudstone, which are interbedded in the sedimentary sequence of the Niigata basin. Reaction p...
Abstract: The nature, composition, and relative abundance of clay minerals in the sandstones of the Brent Group reservoir were studied between 3200–3300 m in a well of the Ellon Field (Alwyn area, Nor...
Abstract: Siltstones from the Precambrian Freda Formation in Wisconsin have been studied by scanning, scanning-transmission and analytical electron microscopy (SEM, STEM and AEM), and X-ray diffractio...
