Buried hydrocarbons:A resource for biogenic methane generation

摘要

Buried hydrocarbons,especially those that cannot be easily and economically recovered,represent a universal opportunity to meet future natural gas needs.We have come to accept landfill gas microbially generated from municipal wastes as a viable means of methane generation.However,we fail to recognize massive coal,shale and residual oil deposits as vast supplies of old biomass that nature has anomalously concentrated for us,just as we concentrate municipal waste in landfills.
