Bowers cross plot - Velocity vs Density

The Velocity vs Density cross plot displays the velocity and acoustic data selected in the Input Logs and Filtering form. The cross plot allows you to have an initial check on the occurrence of unloading. With this information you can decide if the Bowers Method is the correct approach for modeling the pore pressure. The cross plot can be opened via the Input Logs and Filtering form in the 1D Model > Pore Pressure sub-strip.

When specifying the log data to be used as the input for the Bower's Method calculation it is important to quality check and verify the data before proceeding. This cross plot displays the original composite logs in their log colors as defined in the Property Catalog, though a TVDSS overlay can be applied so that depth can also be considered in your data check. The logs can be filtered using lithology and/or boxcar filters and you can elect to display the data unfiltered. To aid in the check of your Velocity vs Density cross plot, the Bower's lower bound and Gardner's Relation upper bound can be displayed.
