Claim 11:
12. A system for determining a pressure profile of a wellbore, the system comprising:
a logging tool configured to be deployed in a wellbore to measure resistivity values as a function of depth along the wellbore; and
a computer configured to perform operations comprising:
receiving data comprising the resistivity values as the function of depth along the wellbore from the logging tool;
identifying a plurality of porous zones from the wellbore based on petrophysical logs by characterizing each identified porous zone based on a porosity amount and a tolerable hole condition;
converting the measured resistivity values to an amount of total dissolved solids for each of the plurality of porous zones;
converting the amount of total dissolved solids to a pore fluid density;
calculating a pressure based on the pore fluid density; and
generating the pressure profile.
