1. n. [Drilling Fluids]
In water analysis, the soluble components in a sample or the residue left after evaporation of a sample. Dissolved solids are reported as ppm or mg/L. Dissolved solids are included in retort solids and can be calculated from chemical analysis results by assuming that all dissolved solids are either NaCl or CaCl2, or a mixture of the two.
See: calcium test, chloride test, milligrams per liter, ppm, retort solids, suspended solids, water, oil, and solids test
