Zisser et al. () examined the relationship between hydraulic permeability and low-frequency (10 mHz to Low-frequency complex electrical response of brine-saturated shaly sandstones book electrical properties of low-permeability sandstones from.

Complex electrical impedance measurements were performed on a brine-saturated Berea sandstone core while oil and CO 2 were injected at different pressures and temperatures.

The saturations of brine, oil, and CO 2 in the core were simultaneously estimated using an X-ray computed tomography scanner. The formation factor of this Berea core and the resistivity Cited by: 4. A look on the electrical resistivity of the common rock-forming minerals (Section ) shows that most of them are characterized by very high able behaviour is expected for low-frequency complex electrical response of brine-saturated shaly sandstones book rocks.

Skip to Main ContentCited by: Shales also form hydrocarbon source rocks and reservoirs, and although numerous methods exist to estimate reservoir properties in sandstones and limestones from electrical measurements (Zinszner and Pellerin, ); there are few validated approaches for using electrical measurements of clay-bearing rocks in a similar way (Myers,Cited by: 7.

The equation was derived from percolation theory in a mechanistic way between clay content and the resistivity response of shaly sand.

According to Waxman and Smits ( Sandstones are mainly quartzarenites; on average, clay minerals constitute about 5 wt.% the whole rock. Although present in minor amounts, clay minerals play an important role in the diagenetic evolution of these sandstones.

Allogenic clay minerals are present in shaly rock fragments and laminae. Early infiltration of clays into porous sabkha. Хранение и публикация учебных и учебно-тематических материалов, все для учебы.
