In this study, the applicability of Microbial Induced Carbonate Precipitation (MICP) to sand control in high-pressure environment assuming methane hydrate reservoir is investigated. The cell culture solution(S.aquimarina, S.newyorkensis) and cementation solution passed through the specimen until the hydraulic conductivity decreased by two order of magnitude. As a result, it was revealed that S.newyorkensis decreases the hydraulic conductivity lower than S.aquimarina in an early stage of injection. In late stage, both S.newyorkensis and S.aquimarina decrease hydraulic conductivity and increase mechanical strength. Our results suggested the applicability of MICP under high confining pressure condition.
