Capture Cross Section of NaCl Water Solutions (high pressures) 

Capture Cross Section of NaCl Water Solutions (high pressures)
Description: The sigma value (Σw) of a saltwater solution can be determined from this chart. The sigma water value is used to calculate the water saturation of a formation. This chart defines sigma water for pressure conditions of ambient through 20,000 psi and temperatures from 68° to 500°F [20° to 260°C]. Enter the appropriate chart for the pressure value with the known water salinity on the y-axis and move horizontally to intersect the formation temperature. The sigma of the formation water for the intersection point is on the x-axis.
