It is the mass of the formation water per unit volume of the formation water and is given in metric units (g/cm<sup>3</sup>). For reservoir engineering calculations, it is considered equivalent to specific gravity.

# Enter the chart along the X-axis using formation temperature.
# Proceed vertically to the appropriate salt concentration expected in the zone.
# Proceed horizontally to read the liquid density at atmospheric pressure.
# Using the “Effects of Pressure” segment of the chart, add a density increment to the above-computed density to correct for pressure effects.
