The densities of these miner als are 35 to 43 lbm/gal
2013 11 8 primary filter cake building filtration control agent in fresh water mud systems. It is a High Yield Natural Sodium Bentonite as per API 13 A (Section 9 ) used as a weighing agent and increases viscosity in the oil field applications. It is used in drilling mud for control ling borehole stability and extracting drill cuttings from the bit.
The primary use for biopolymers is as a rheology control agent. They develop high, low shear rate viscosities useful for suspension and carry ing capacity. (c) Guur gum polysaccharide manufactured from the endosperm of the seed of the guar plant. It has a complex structure with a high molecular weight (Chilingar and Croushorn, 1964).

2019 6 6 Pectin (from Ancient Greek pktiks, "congealed, curdled") is a structural heteropolysaccharide contained in the primary cell walls of terrestrial plants.It was first isolated and described in 1825 by Henri Braconnot. It is produced commercially as a white to light brown powder, mainly extracted from citrus fruits, and is used in food as a gelling agent, particularly in
Thickening agent A thickening agent or thickener is a substance which can increase the viscosity of a liquid without substantially changing its other properties. Edible thickeners are commonly used to thicken sauces , soups , and puddings without altering their taste; thickeners are also used in paints , inks , explosives , and cosmetics .
