Abstract

A method of estimating downhole fluid properties includes deploying a borehole string in a borehole in a resource bearing formation, simulating a downhole fluid property distribution along a length of the borehole string using a mathematical hydraulics model, the fluid property distribution related to downhole fluid pressure, measuring a downhole fluid property related to downhole fluid pressure at a selected location along the length of the borehole string to generate a measured fluid property value, and comparing the measured fluid property value to a simulated downhole fluid property at the selected location. The method also includes calculating a correction value based on a difference between the measured fluid property value and the simulated fluid property value at the selected location, correcting an entirety of the fluid property distribution along the length based on the correction value, and controlling a downhole operation based on the corrected fluid property distribution.
