Title: Enabling Materials and Corrosion Technologies for Gas Developments


1
Enabling Materials and Corrosion Technologies for
Gas Developments
7th Natural Gas Conference Exhibition March 9
- March 12, 2009 Doha, Qatar
  • Eric J. Wright
  • ExxonMobil Development Company
  • Houston, Texas, USA

Presentation Outline
  • Role of ExxonMobil Development Company
  • Technology Engagement
  • Technology Qualification Examples
  • Full Wellstream Flowline and Pipelines
  • Subsea Cryogenic Loading Lines
  • Conclusions

3
Role of ExxonMobil Development Co.
  • Plan and execute all major oil and gas upstream
    developments for ExxonMobil worldwide
  • Global, functional approach to engage technology
  • Working alone and with venture partners,
    implementing 100 plus major development projects
  • Identify opportunities for improved business
    solutions

4
Technology Transfer
  • Leverage expertise and global specifications
  • Identify technology opportunities
  • Qualify technologies
  • Apply Lessons learned

5
Technology Qualification - Examples
  • Full wellstream production
  • Subsea cryogenic transfer

6
Full Wellstream Incentive Challenge
  • Incentive
  • Elimination of offshore dehydration while using
    carbon steel for large savings
  • Challenge
  • Full wellstream is highly corrosive
  • Strategy
  • Design, qualify chemical treatment program

Full Wellstream Corrosion Control
  • Define the Environment
  • Define flow regimes
  • Define fluid chemistry
  • Qualify Corrosion Control
  • Simulate environment
  • Qualify corrosion control
  • Transfer to Operations
  • Corrosion Manual
  • On site training

Flow and Liquid Entrainment
Enabled savings for multiple sour gas projects

36NiFe Line Incentives Challenges
  • Incentives
  • Longer loading line
  • Lower costs
  • Less environmental impact
  • Challenges
  • Pipe product unavailable
  • Fabrication welding
  • Strategy
  • Design and prototype with suppliers and pipe
    mills

Conclusions
  • Materials and corrosion technologies impact
    project design/economics early engagement is
    valuable
  • Technology transfer requires an organization of
    integrated expertise and a suite of
    specifications
  • Technology requires a rigorous qualification
    program
  • Stakeholder engagement is needed to
  • Effectively qualify the technology
  • Communicate the technology design limits
  • Transfer the associated operating practices
  • This approach captures the technology benefits
