n: A colloidal, viscosity-building clay used principally in salt-water muds.

a colloidal, viscosity building clay used in water based muds. They generate viscosity due to the mechanical interference of their straw shaped bodies.

n: the electrical resistance offered to the passage of current;the opposite of conductivity.

n: the electrical resistance offered to the passage of a current, expressed in ohm-meter;the reciprocal of conductivity. Fresh-water muds are usually characterized by high resistivity, salt-water muds by a low resistivity.

measurement of a substance (or rock) to resist the flow of electric charge. Opposite of Conductance.

n: a drilling fluid containing dissolved salt (brackish to saturated). These fluids may also include native solids, oil and/or such commercial additives as clays, starch, etc.
