1. Subsea Production Assurance A new generation of Smart Qualified Subsea Flow Assurance Integrity Monitoring Tools

2. The flow assurance integrity challenge Deeper water/remote reservoirs –hotter, higher pressure, corrosive, hydrate susceptibility, sand producing and stranded, remote with prohibitive intervention costs Longer tiebacks and multiphase transportation –corrosion and scale –plugging (hydrate precipitation and organic solids formation due to thermal/hydraulic profiles) –sand erosion damage and accumulation

3. …the challenge Brownfield decline and increased high risk marginal fields Commingling of unprocessed well streams can lead to increased risk of fluids incompatibility and raises partner/joint venture issues in sharing infrastructure Environmental and H&S regulatory – increasing governmental constraints

4. The Smart digital oil field New technologies destined to transform the offshore industry 4D seismic, smart wells, intelligent completions high bandwidth HTHP deepwater qualified seamless integration of S3-Monitoring and modeling M2 remote 3D virtual visualization

12. Flow assurance integrity modelling and simulation Flow assurance integrity modelling ensures technical, operational and HSE integrity during design and operation of production systems throughout the entire life cycle. This results in overall capital and operating cost effectiveness. Successful design and operation of multiphase production systems rely on detailed understanding of flow behaviour

13. The Impact of Flow Assurance Integrity Technologies Integrated subsea real-time Flow Assurance Integrity monitoring correlated with modelled simulations evolve optimized intervention strategies enable RISK to be managed with Accelerated production and improved ultimate recovery Longer tiebacks - increased flow assurance integrity and reduced capex Economically viable developments Proactive intervention/maintenance - reduced opex
