Technical Paper: Enabling Subsea Surveillance: Embracing ‘True Production Control’ With An Open Architecture Subsea Monitoring And Control System

Society: Other
Paper Number: 074
Presentation Date: 2006


The increase in data provided by advanced surveillance systems, such as the new Subsea Monitoring and Control (SMC) platform (Amin et al 2004), allows innovative ways to monitor subsea systems and production operations extending from the sand-face to the host facilities. This enables productivity optimisation through closed loop actions based on factual real-time information. The combination of real-time data acquired from subsea monitoring systems with modelled and historical data, expert analysis and real-time productivity optimisation tools, provides the operator with detailed analysis of production and hardware performance. It allows interventions and production operations to be planned more efficiently, thereby reducing downtime, production loss and operating expenses. In the last few years, the industry has dramatically increased the number of intelligent seabed and downhole monitoring devices in the subsea industry with the introduction and acceptance of multiphase flow metering, fibre optic temperature and flow sensors, intelligent well flow control devices and similar systems. Exploration and production (E&P) companies have launched a number of initiatives to develop smart-field technologies, infrastructures, data visualisation and analysis applications. This paper will review the application of SMC as an enabler for the subsea surveillance solution and focus on the benefits of an open, transparent and high-speed subsea area network. The paper will demonstrate how the resulting improvements in subsystem interface engineering, system reliability and production optimisation could relate to economic gains in both capital expenditure (CAPEX) and operational expenditure (OPEX) phases of future subsea field developments.
