Transcript

  • 1. Oil Exploration &amp; Extraction<br />John Herbst<br />CEM Advisory Panel<br />April 27-28, 2010<br />
  • 2. Presentation Overview<br />Technology Overview &amp; Relevance<br />CEM Research Activities<br />Electromagnetic Vibrator<br />Electric Valve Actuator<br />Subsea Production Systems<br />Offshore Power Generation/Distribution<br />Hyperbaric Test Facility<br />Upcoming Milestones<br />
  • 3. Technology Relevance<br />Most of the “easy” oil and gas reserves have been identified<br />Locating and exploiting future reservoirs will require drilling and production in more challenging environments<br />“Tight” formations<br />Deeper water/higher pressures<br />Longer offsets<br />CEM Research<br />Electric valve actuation<br />EM Vibro-seismic sources<br />Subsea/Offshore production<br />Power transmission/conversion<br />Source: Aker Solutions<br />Source: http://www.hydro.com/library/images/press_room/news/2003_11/Ormen_1800.jpg<br />
  • 4. Electromagnetic Vibrator<br />New technology advancing the exploration for oil &amp; gas<br />Replaces existing vibro-seismic technology based on hydraulic actuators<br />Uses EM forces to generate source waves<br />Higher force, lower frequency and higher fidelity are potential improvements to existing technology<br />
  • 5. Ground Force Simulations<br />Simulation model does not include the natural resonance of the base plate (~175 Hz). Model DOES include earth resonance (~39 Hz)<br />Expected spectral performance of proof-of-concept system is good<br />Figure shows 60 Kip force for full sweep<br />Bottom figure shows waveform details at ~120 Hz<br /> PWM delivers good harmonic resolution<br />Proof-of-concept system will produce 60 Kips on soils comparable to sand (or harder)<br />Detailed high resolution models in Matlab were used to guide the development<br />5<br />
  • 6. EM Vibrator Conclusions<br />Design, construction, and assembly of the electromagnetic vibrator is complete<br />Integration on an existing truck is complete<br />Initial testing has just begun and we plan to test the full functionality of this new oil and gas exploration technology<br />
  • 7. Electric Valve Actuation<br />Wellhead valves have typically been hydraulically actuated with failsafe spring closure<br />Operation at higher pressures requires larger springs<br />Discharge of hydraulic fluid is prohibited in many areas<br />Zero tolerance in North Sea<br />CEM developed designs for all-electric valve actuators <br />http://www.spe.org/jpt/2006/10/all-electric-subsea-production-system/<br />
  • 8. Subsea Production Systems<br />Subsea production processes<br />Multi-phase pumping<br />Re-injection pumping<br />Separation<br />Gas compression<br />Multi-megawatt power levels<br />Technologies<br />Barrier fluid filled motors<br />Induction motors<br />Permanent magnet motors<br />Power distribution/control <br />1.8 MW Subsea Pumps<br />http://www.intsok.no/docroot/downloads/Framo--PDF-7--Subsea-Pump-Proje.pdf<br />
  • 9. Integrated Compression Systems<br />Direct drive compressor with integral high speed electric motor<br />Single pressure housing<br />Eliminates high ΔP seal<br />Leveraging CEM experience with high speed, high power density electric machines<br />Example of GE Integrated Compressor<br />http://www.gepower.com/businesses/ge_oilandgas/en/literature/en/downloads/integrated_compressor_line.pdf<br />
  • 10. Subsea Separation/Boosting System<br />
  • 11. Flooded Motor Technology Evaluation<br />CEM evaluation favors synchronous PM motor over induction motors for subsea applications<br />Pros<br />Power factor<br />Efficiency<br />Physical airgap<br />Cons<br />Power density<br />
  • 12. Motor Comparisons<br />
  • 13. Motor Comparisons<br />
  • 14. Offshore Power Generation &amp; Distribution Systems<br />Typical Floating Production, Storage and Offloading (FPSO) ship has ~100 MW power generation<br />Pumps and compressors are major loads<br />Leveraging ESRDC experience in modeling of ship power systems to explore novel offshore power system topologies<br />
  • 15. Statoil Troll A Platform<br />Statoil’s Troll A Platform off coast of Norway<br />ABB HVDC Light power distribution from shore<br />~85 MW of electrical power <br />~70 km offset<br />
  • 16. Offshore Power Transmission &amp; Distribution Systems<br />Eliminate FPSO or fixed platform by providing tie-back to shore<br />Eliminates cost/risk of topside installation<br />Efficient power generation on shore<br />Requires subsea production system<br />Motors, pumps, separators, compressors, valves, etc.<br />Communications &amp; control<br />Power distribution &amp; conversion<br />
  • 17. CEM Hyperbaric Test Facility<br />ASME Code rated:<br /> 10,000 psi, 400°F<br />Interior dimensions:<br />19” Ø x 58” L<br />14 penetrations<br />Instrumentation<br />Power supply<br />Hydraulics<br />
  • 18. Upcoming Milestones<br />Field testing of EM vibrator<br />May – June 2010<br />Production prototype of EM vibrator<br />Projected program start August 2010<br />Certification and commissioning of hyperbaric chamber<br />Scheduled for May 2010<br />
  • 19. Summary<br />CEM is conducting state-of-the-art research to support exploration and production of challenging oil and gas reserves<br />Developing major new research programs in this area<br />Research leverages CEM’s core technologies<br />Power system modeling and simulation<br />High power density electric machines<br />Electric actuators<br />Power generation, distribution, and conversion<br />CEM is building a 10,000 psi hyperbaric test facility to support future research in this area<br />
