Subsea Production Assurance

A new generation of Smart Qualified Subsea Flow Assurance

Integrity Monitoring Tools

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

…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

The Smart digital oil fieldNew 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

Subsea flow assurance integrity monitoring technology

• Sub-surface monitoring – downhole PT

• Wellhead – MPFM, Pressure Temperature Transmitters, Sand Probe, Choke Bridge Condition Monitor

• Flow-lines, manifold, risers – Pressure temperature, Corrosion Probe, Flow Assurance Probe/Spool

Sand Management - Probes

• Intrusive sand erosion with P & T only

• Intrusive direct erosion measurement with intrusive acoustic for sand rate, mass flow with P and T

• Non-intrusive acoustic for sand rate only

Sand management – modelling and prediction

• Integrated sensor detects sand impacts through acoustics and directly correlate with erosion, flow force with P&T

• Model sand flow regime and characterise well and risk to system

• Model sand accumulation through the network

Choke bridge condition monitoring

• Sand erosion sand rate, pressure and temperature

• Detects preferential flow at exit from choke valve

• Integrated into one module to SCM

Pipeline integrity management - Corrosion monitoring spools

• On-line inspection tool - FSM 0.1% wall thickness

• Real-time monitoring tool RPCM™ 0.005% wall thickness complete with pressure and circumferential temperature profile

• Locations subsea flowlines & pipelines

Flow Assurance Integrity management – single point sensor

Integrated multi-array subsea sensor measures metal loss (CEION), P&T, mass flow force, acoustics (sand or hydrates), solution conductivity and heat transfer

Applications include• Hydrate precipitation and formation

detection• Organic solids deposition detection• Scale detection• Under deposit corrosion measurement• Erosion-corrosion-sand correlation

Flow Assurance Integrity management – spool piece

Integrated multi-array spool piece sensor measures metal loss (CEION RPCM™), differential pressure, circumferential temperature, acoustics (sand or hydrates), solution conductivity and heat transfer

Applications include• Corrosivity profile and under

deposit localised corrosion measurement

• Erosion-corrosion-sand correlation• Hydrate, Organic solids deposition

and Scale detection• Slug flow and liquid hold-up

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

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
