2. Introduction The overlap between the oil and gas industry and CEM technology is broad Focus for coming year in four areas – Homopolar welding cost reduction – Vibroseis commercialization – Deep sea production technology development – Pumping technology improvements

3. The CEM Niche High power motors and generators Isolated power grids High power electromagnetic actuators for exploration Electromagnetic pipeline welding Operation of electrical system components at high pressure 3

4. Two Projects Commercially Sensitive Vibroseis – Prototype built – Extensive field testing – Performance being evaluated by sponsor and other investors Motors/Generators – Assessing new technology to improve reliability

5. Homopolar Welding Key research challenge – Manufacturing for production Prototype built and demonstrated Lower cost would reduce barrier to adoption Key applications – Tube welding for deep sea applications – Welding of irregular shapes – Welding of special alloys 5

6. Homopolar Welding Demonstration

7. What we have done… We have conducted several welding, billet heating, sintering and spot welding programs – NSF basic research to determine weldability of metals – EPRI boiling water reactor pipe – Railroad rail welding – ASTEC Industry alloy steel heat exchanger tubing – OIME oil field pipe welding – Sintered several metal powders Aluminum alloys Copper graphite Metglas Tungsten – Billet heating – Joint Industrial Program (JIP) pipeline welding 7

8. How we plan to develop this field Vision of the role CEM can play – Design and fabrication of an inexpensive HPG Who might our partners be – Industries with specialized welding problems Deep sea exploration Railroads Automotive Near-term steps to achieve the vision – Start a program with private industry – Pursue funding from NSF, ARPE-e, or other science-related programs 8

9. Deep Sea Production Most of the “easy” oil and gas reserves have been identified Locating and exploiting future reservoirs will require drilling and production in more challenging environments – “Tight” formations – Deeper water/higher pressures – Longer offsets CEM Research – Electric subsea valve actuation – Subsea/Offshore production – Power transmission/conversion

10. Relevant CEM Experience Pumps and compressors are electrical major loads – Advanced motors and drives are CEM core technologies – Typical Floating Production, Storage and Offloading (FPSO) ship has ~100 MW power generation Comparable to Navy surface combatant or land-based DOD installation Ship power system design and technology Microgrid modeling, testing, and control Testing under high ambient pressure

11. Key Facilities Hyperbaric test chamber – 10,000 psi, 400° F – 19” Ø x 58” L – 14 penetrations Instrumentation and power Liquid heating/cooling Microgrid – AC or dc – Up to 1 MW

12. Summary This is an application area that leverages CEM experience Two projects focused on commercialization – One this year – One several years out Developing three research projects – Homopolar welding – Sea floor power systems – Efficient platform power 12
