  • Collaborations
    • I was a visiting researcher at the GFZ-Potsdam research center for 6 months conducting research on methane hydrate formation and dissociation on a small scale via Raman spectroscopy and Microscopy.  Read more about the project here.
  • Description of Research
    • My research will continue our investigations into a novel approach to methane recovery from natural gas hydrates while depositing GHG for permanent sequestration. The research project here is to investigate and develop a novel concept of generating a point heat source, via in-situ combustion, strategically located in the hydrate deposit which enables methane production where only about 10% of the energy content that is produced from the reservoir is used for the process. This combustion process is capable of utilizing CO2 as a diluent to adjust adiabatic temperatures to the point where methane hydrates decompose, yet CO2 hydrates still can form and replace methane. The research is conducted in a 72 liter, high pressure vessel capable of simulating the low temperatures and high pressures required for stable methane hydrate production and dissociation.
