Enhanced Natural Gas Recovery

Injecting captured carbon dioxide into unconventional reservoirs allows for both permanent storage of carbon and enhanced recovery of natural gas and oil—but large-scale implementation requires further research. We are currently working on:

  • Coalbed methane and shale gas recovery
  • Mechanisms of carbon sequestration in geologic strata
  • Applications for mine degasification
  • Energy policy
  • Seismic responses to gas production
