Water solids concentration
The concentration of solids in formation water (brines) are reported in several different ways [1].
Math and Physics
Conversions
Often, parts per million and milligrams per liter are used interchangeably. This is correct only if the density of the brine at standard conditions can be assumed to be 1 g/cc ( 1000 kg/m3, SG_w=1, 62.428 lbm/ft3) [1].
Nomenclature
= water salinity or solids concentration, ppm
= water salinity or solids concentration, mg/l
= water salinity or weight percent solids, %
= water specific gravity, dimensionless
