Abstract

Methane hydrate (MH) is one of the potential resources of natural gas. In this study, we have conducted the field scale simulation to clarify permeability characteristics and gas production behavior during MH dissociation process in marine sediments. Reservoir model is based on the field data for Nankai Trough area in the adjacent Sea of Japan, and characterized by permeability anisotropy due to alternation of strata consisting of sand and mud layers. Some simulation runs were conducted, changing the relative permeability as calculation parameter. Based on calculation results, we considered the effect of this parameter on MH dissociation and gas production behavior.
