n: a measure of the ability of a colloidal dispersion to develop and retain a gel form, based on its resistance to shear. The gel. or shear, strength of a drilling mud determines its ability to hold solids in suspension. Sometimes bentonite and other colloidal clays are added to drilling fluid to increase its gel strength.

n: a parameter used to measure the shear strength of the mud and its ability to hold solids suspension.bentonite and other colloidal clays are added to the mud to increase gel strength.

the ability of a fluid to suspend solids.

n: The study of the physical characteristics and behavior of rock. rock mechanics can include analysis of and relationships between properties such as velocity, density, porosity, permeability, shear strength, and bending and crushing behavior, as well as th

the study of mechanical rock behaviors under changing loads and stresses.

the stress level at which rock fails under shearing or distorting load. Generally the same as compressive strength.

n: see gel strength.

n: a measure of the shear value of fluid. The nminimum shearing stress that will produce permanent deformation. See gel strength.

the minimum shear stress that will produce permanent deformation of the fluid (gel breaking).

n: an instrument used to measure the shear strength, or gel strength, of a drilling fluid. See gel strength.

n: The equipment be used to measure the shear intensity of drilling fluid.
