Improving the Communication Network Reliability at Electric Submersible Pump Wells Offshore using SCADA

Problems faced by monitoring and control system at Electric Submersible Pump (ESP) wells offshore in PHE ONWJ has been the unreliability of communication network and random delays, which result in some data from ESP wells, were not saved by the database. As a solution, Supervisory Control and Data Acquisition (SCADA) is employed to monitor and control ESP wells offshore in real time. It consists of three main parts, Master Terminal Unit, Remote Terminal Unit, and communication media (link). MTU controls the communication by sending commands (queries). RTU responds to the command and send the condition of the plant. Communication between them uses Modbus protocol communication rules. This paper reports the improvement of communication network reliability at offshore pumping wells using SCADA along with it’s remote maintenance by introducing the IoT. The results show the reliability of communication has been improved and the process at the offshore can be monitored remotely; however, some of the sensors need to be replaced.
