The Rw vs. Temperature Interactive Crossplot has been updated. This crossplot displays water resistivity (Rw) as a function of temperature and now includes solution concentration outputs in mg/L and ppm (salinity), as well as solution density. These outputs allow a direct comparison to water analysis reports, making Rw assignment easier.
A chart which presents water resistivity (Rw) at 25 deg. C vs. NaCl salinity, based on Schlumberger's Gen 9 chart is now available. With this chart, it is easy to determine Rw at a given salinity (the original Gen 9 Chart requires the user to follow a line across a large temperature range, making accuracy difficult, especially at high salinities).
A NaCl solution density at 25 deg. C vs. NaCl concentration (ppm and mg/L) chart is now available. This chart is useful because it allows the user to determine solution density at a given NaCl concentration, which then enables conversion from mg/L to ppm, or vice versa.
Poisson's Ratio vs. Compressional to Shear Velocity Ratio (VPVS) Interactive Crossplot has been added. This crossplot is used to determine Poisson's ratio and identify intervals which might be affected by light hydrocarbon.
