Permanent down Hole Gauges (PDHGs) are typically run in combination with Distributed Temperature Sensing (DTS) cable with Wellbore Segmentation using Swellable Packers. The interpretation of the signals of the DTS/PDHG is complex, but it provides the possibility to identify change in production / injection profile along the completion and changes to the composition of produced fluids. Permanent down Hole Gauges (PDHGs) is a system enables the user to measure the reservoir pressure and temperature at single fixed point on real time basis. Distributed Temperature Sensing (DTS) is a technology which provides the user with a technique to measure the temperature in a well (from the surface to the TD of the well) distributed along the fibre optic line at any time.

Several challenges were anticipated and measures were taken to minimize the risks of such implementation to ensure smooth deployment successfully.
