H074:
Influence of Biomineralization on Porous Media Hydrodynamics





Session ID#: 23075

Session Description:
Microbially catalyzed mineral precipitation (biomineralization) has diverse subsurface applications, including soil strengthening, groundwater remediation and near-well fracture sealing. The success of subsurface biomineralization applications is influenced by micro- and macro-scale transport and reaction dynamics. For example, microbial growth and mineral precipitation inevitably change porous media geometry and hydrodynamics, which in turn alter the transport potential of microbes and substrates for biomineralization.  Thus, an interplay between microbial transport, fluid flow, chemical transport, reaction kinetics, and porous medium geometry ultimately controls the distribution of mineral, microbes and permeability.  Abstracts are sought on studies of microbially induced mineral precipitation in porous media, including laboratory experimental studies, field tests and modeling efforts.  Specifically, topics of interest include transport and delivery of microorganisms, reactive transport dynamics during precipitation in porous media, advanced imaging of pore-scale changes and computational modeling of microbially induced mineral precipitation.
