... to decrease the pore pressure which, in turn, releases the gas in place. A MECBM reservoir requires treating the coal in situ with nutritionally-amended microbial solutions, and allowing it to produce biogenic methane over the treatment duration. Post-treatment, the behavior of a MECBM reservoir is expected...
