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
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
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
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

Homopolar Welding Demonstration
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

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
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
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
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

There is some flexibility with this module; it is shown as another controlled load but we could
potentially implement or emulate energy storage and show power flow in both directions.

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
