n: a drilling fluid made up mainly of chemical salts, such as sodium chloride, calcium chloride, or potassium chloride. Clear brine contains little or no clay or other solid material and is virtually transparent. It is often used when drilling into a producing formation because clear brine minimises formation damage. See completion fluid formation damage.

a brine without suspended solids.

n: a porous medium through which a fluid is passed to separate particles of suspended solids from it.

n: refer tofilteration

n: the process of filtering a fluid.

n: The process of separation of suspended solids from liquid by forcing the liquid through a porous medium while screening back the solids. Two types of fluid filtration occur in a well: dynamic filtration while circulating, and static filtration when the fl

mud with a low suspended solids quantity. It may be formulated with a brine with high density created by dissolved salt.

n: determination of the relative percentages of substances, e.g., the suspended solids in a drilling fluid that pass through or are retained on a sequence of screens of decreasing mesh size. Also called sieve analysis.

n: The solid phase grains in the drilling fluid pass different sizes screen for knowing the distribution of sizes .


particle size distribution of a sand sample made by running the sample through a set of screens.

total suspended solids in a quantity of liquid.

a measurement of fluid clarity. Suspended solids and color in water reduces light transmission. Turbidity is a comparison of the amount of light that passes through a trial fluid compared to a clear sample.
