Claim 0:
1. A method for determining a pressure profile in a subterranean formation, the method comprising:
drilling a wellbore in the subterranean formation;
lowering a logging tool into the wellbore to measure resistivity values as a function of depth along the wellbore;
identifying a plurality of porous zones from the wellbore based on petrophysical logs, wherein identifying the plurality of porous zones further comprises 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 a sum of the pore fluid densities derived along a length of the well; and
generating a depth-based pressure profile.
