Phase VIII

1
Phase VIII

• 2006-2007

2
Phase VIII

• Mission StatementFacilitate a cooperative,
  globally aligned effort focused on identification
  development of economically viable, methods to
  drill, produce and transport hydrocarbons from
  deepwater. DeepStar Phase VIII focus is on 4,000
  to 10,000 feet water depth with a global
  application.
• Focus
• Are the technologies that address the following
  key challenges.
• This does not preclude other innovative
  technology solutions that have significant
  deepwater business impact being adopted by
  DeepStar in Phase VIII

3
Phase VIII Focus Key Challenges

• Enhanced well productivity and recovery
• Subsea boosting
• Artificial lift for heavier oils
• Water management EOR and disposal
• High drawdown completion reliability
• Multiphase Subsea metering
• Flow assurance
• Asphaltene disposition prediction and management
• Viscosity and emulsion management
• Hydrate kinetics plugging
• Cold flow
• HPHT systems
• Enhance 15k capabilities HIPPS
• Enable 20k capability - FA tools, subsea,
  drilling completion capability
• Alternate riser systems

4
Phase VIII Focus Key Challenges

• Reliable/enhanced deepwater production systems
• Global performance (global analysis, VIV
  riser/hull, system)
• Risers fatigue/reliability, alternative
  systems, installation methods
• Early production system
• Gas Management
• GOM Regulatory
• Riser for FPSO
• Well cost reduction
• Well construction - Well bore stability (casing
  point elimination), casing integrity
• Quicker completion system deployment
• HPHT capabilities (gt15k)
• General
• Loop Eddy current management for production and
  to drilling
• Improve the economic threshold for small fields
• Delivering on the 50 mile tie back challenge for
  oil
• Operability of systems availability
  reliability
