The PetroCalc applications provide an interactive environment to
solve for reservoir parameters based on well log and core data (click on the links below for examples of these calculations)

Through the PetroCalc application the user can calculate (click on the hyperlinks for more information):

• Vshale Tab for calculating clay volume
• Porosity Tab for calculation of total porosity
• Rt, Rxo, Sxo Tab for invaded zone resistivity and corrected
• Lithology Tab for identifying the rock fabric of the reservoir
• Water Sat Tab has various methods for solving water saturation from resistivity logs
• Perm Tab has models for mapping log data to permeability
• BH Tab has controls to avoid bad-hole sections
• Coal Tab has controls to flag coal sections
