Abstract
This paper describes how a wireless sensor network(WSN) was deployed at the Gullfaks offshore Oil &Gas facilities in the North Sea. At the Gullfaks field,decline in flow line pressure occasionally causes lossof flow from wells. This is not readily detected, andleads to large financial losses. The installation andmaintenance of a traditional detection system is costly,complex and requires a production shutdown. Instead, wireless temperature sensors are used topredict the loss of flow from a well. Before deployment,the solution was tested in a semi-industrialenvironment to ensure that it fulfilled all requirements. The conclusion is that the described WSN solutionenabled quick and reliable detection of lost flow, thusenabling prompt action to re-establish this.
