Low Gravity Solids

Definition - What does Low Gravity Solids mean?

Low Gravity Solids are a type of drilling fluid solids which have a lower density. The density is usually lower than the density of hematite or barite that is used to weigh up the drilling fluid. A drilling fluid usually contains drill solids as well as bentonite clay. The density of low gravity solids is approximately 2.60 gram per cubic centimeter.

Petropedia explains Low Gravity Solids

The solid content is usually a fraction of the total density in drilling mud, and it always increases while drilling because of cuttings, mud chemical additives and weighting material. The solid content usually refers to the soluble and insoluble solid content in the drilling fluid system. The concentration of low gravity solids in drilling fluids is calculated by mud engineers on the basis of analyzing the drilling mud, mud weight, retort analysis, chloride titrations and other types of information. The solids are reported as pounds per barrel or volume percentage. The concentration of water and hematite is usually 1.0, barite 4.20 and 5.505 gram per cubic centimeter respectively.
