Electrical resistivity anomalies over hydrocarbon bearing structures

Electrical resistivity and tunneling anomalies in CeCuAs2

The compound CeCuAs2 is found to exhibit negative temperature (T) coefficient of electrical resistivity (ρ) under ambient pressure conditions in the entire T-range of investigation (45 mK to 300 K), even in the presence of high magnetic fields. Preliminary tunneling spectroscopic measurements indicate the existence of a psuedo-gap at least at low temperatures, thereby implying that this compoun...

the study of effect of confining pressure on electrical resistivity of hydrocarbon reservoirs rocks

the electrical resistivity of hydrocarbon reservoir rocks is an important parameters in the calculation of water and oil saturation percent in both carbonate and sandstone reservoir rocks.in this regard, most studies have concentrated on the confining  pressure on cementation factor and electrical resistivity in sandstone reservoir rocks. in this study the effect of confining pressure on cement...

Hydrogeophysical Approach for Identification of Layered Structures of the Vadose Zone from Electrical Resistivity Data

1 Heterogeneity and lack of sufficient site characterization render accurate and reliable predictions of subsurface flow and transport in the vadose zone notoriously elusive. It is now widely recognized that for quantitative descriptions of subsurface phenomena to be scientifically defensible, they have to be accompanied by some measure of predictive uncertainty. In other words, a major goal of...

Morphology and electrical resistivity of metallic nanostructures

The electrical resistivity r of Au, Al and Cu films prepared by thermal evaporation with thickness range from 3 to 100 nm on glass substrates were studied. The r value was measured and theoretically evaluated by the Fuchs–Sondheimer (F–S), the Mayadas–Shatzkes (M–S), and the combined models. Measured r values in Al films were about seven times minor than for Au and Cu films for the minimum (3 n...
