This thesis studies the impact of wired drill pipe telemetry on the Martin Linge field. In addition, the utilization of along string measurements will be analysed and a verification will be made on both how far the technology has come, and the way forward. The reliability trends for the wired drill pipe telemetry system on Martin Linge are positive. The reliability rates achieved, currently averaging 91% uptime, might be one of the highest on the Norwegian Continental Shelf so far. Uptime is a very important aspect of the wired drill pipe telemetry system, and it is important to put a focus on how to increase it. Having a third party responsible for the uptime has introduced a whole new incentive for increasing, and maintaining, stable uptime. Early start-up of the utilization of wired drill pipe telemetry has familiarized everyone with the equipment and handling of the tools, and has contributed to the network uptime gradually increasing. Several examples of how to use the along string measurement pressure sensors will be presented, with respect to pack-off detection, hole cleaning, lost circulation and leak off testing. These can be used as means of analysing downhole data in real-time and used as a basis for software development. In the end, high speed transfer of data between downhole tools and surface are reducing telemetry time and saving rig time. Currently, a reduction in telemetry time of 5.87 [hours/1000m drilled] has been achieved. Thus, a lot of cost has been saved by decreasing time spent on downhole communication.
