Water solids concentration

The concentration of solids in formation water (brines) are reported in several different ways [1].

Math and Physics

 C_{ppm} = \frac{gram\ solid}{10^6\ gram\ water}
 C_{mg/l} = \frac{milligram\ solid}{litre\ water}
 C_W = \frac{gram\ solid}{100\ gram\ water}

Conversions

 C_{mg/l} = C_{ppm}\ SG_w
 C_W = C_{ppm}/10000

Nomenclature

 C_{ppm} = water salinity / solids concentration, ppm
 C_{mg/l} = water salinity / solids concentration, mg/l
 C_W = weight percent solids, %
 SG_w = water specific gravity, dimensionless
