The Lowdown on Low

resistivity pay was, practically speaking, a contradiction in terms Their pioneering research hinged on the principle that gas- or oil-filled rocks have a higher resistivity than water-filled rocks Through the years, how-ever, low-resistivity pay has become recog-nized as a worldwide phenomenon, occur-ring in basins from the North Sea and...

Application of electrical resistivity

The ground resistivity is related to various geological parameters such as the mineral and fluid content, porosity and degree of water saturation in the rock Electrical resistivity surveys have been used for many decades in hydro geological, mining and geotechnical investigations More recently, it has been used for environmental surveys...

THERMAL PROPERTIES OF ROCKS

rock-forming minerals It is anticipated that values of these thermal properties of rocks and minerals will be useful for radioactive waste management, heat flow studies, and geothermal resource appraisals, and other thermal problems in the earth...

Earth exploration

The resistivity of most rocks varies with porosity, the salinity of the interstitial fluid, and certain other factors Rocks containing appreciable clay usually have low resistivity The resistivity of rocks containing conducting minerals such as sulfide ores and graphitized or pyritized rocks depends on the connectivity of the minerals present...

Formation Resistivity Factor

where R o is the resistivity (ability to impede the flow electric current) of a brine-saturated rock sample in ohm-m, R w is the resistivity of the saturating brine in ohm-m, and F R is dimensionless The formation resistivity factor, which is always greater than one, is a function of the porosity of the rock (amount of brine), pore structure, and pore size distribution...

Electrical Properties: Mineral Properties

Conduction Conduction in mineral terms is defined as the ability of a mineral to conduct electricityOnly a very small number of minerals are good conductors; they are the metallic elements and the mineral GraphiteThese conductors can be placed between a wire carrying electricity, and ,...

RESISTIVITY OF ROCKS and ARCHIE'S LAW

RESISTIVITY OF ROCKS and ARCHIE'S LAW For rocks composed of non-conducting matrix minerals and saturated with water, an empirical relationship known as Archie's Law is useful in analysis of electrical properti Archie's Law is commonly written (2-1) where FLUID equals the electrical properties of the fluid in the pores, F is the porosity (ratio of void volume/total volume), and A and m ,...
