ABSTRACT:
An apparatus and method for use in determining pressure at a formation of interest in-situ. A carrier carrying a tool is conveyed in a borehole. The tool includes a sealing member and a port exposable to the formation of interest. A formation fluid sampling chamber is separated from a hydraulic fluid chamber by a flexible member that allows pressure communication from the fluid sampling chamber to the hydraulic fluid chamber. A sensor senses pressure in the hydraulic fluid for determining pressure in the sampling chamber.
