description A method and apparatus is provided to determine downhole pressures, such as annular pressure and/or pore pressure, during a drilling operation. A downhole drilling tool includes at least one conduit and a corresponding gauge. The conduit is positioned in the downhole tool and has an opening adapted to receive downhole fluids. The conduit is positionable in fluid communication with one of the wellbore and the formation whereby pressure is equalized therebetween. The gauge is provided for measuring the pressure in the conduit.
