The electronic conductivity of purified distilled water in electrochemical laboratory settings at room temperature is often between 0.05 and 1 μS/cm. Environmental influences during the preparation of salt solutions as gas absorption due to storing the water in an unsealed beaker may immediately increase the conductivity from 0.055 μS/cm and ...
In the following table, material data are given with a pressure of 611.7 Pa (equivalent to 0.006117 bar). Up to a temperature of 0.01 °C, the triple point of water, water normally exists as ice, except for supercooled water, for which one data point is tabulated here. At the triple point, ice can exist together with both liquid water and vapor.
These salts can get added to the water / steam from atmosphere or due to leakages in heat exchangers etc. The conductivity of ultra pure water is almost close to zero(as low as 0.05 microsiemens/cm), while with addition of even 1 ppm of any salt, the conductivity can shoot up to even more than 100 micro siemens/cm.
SP data can be used to find: Depths of permeable formations; The boundaries of these formations; Correlation of formations when compared with data from other analogue wells; Values for the formation-water resistivity; The SP curve can be influenced by various factors both in the formation and introduced into the wellbore by the drilling process.

The usual units are volts (V) or, more commonly, millivolts (mV). From a theoretical viewpoint, the zeta potential is the electric potential in the interfacial double layer (DL) at the location of the slipping plane relative to a point in the bulk fluid away from the interface.
