  • Prevention of biomass aggregation at injection wells
    Patent number: 8720546
    Abstract: Disclosed herein is introduction of different nutrient solution formulations to a subterranean target site to prevent biofilm formation and biomass aggregation at the sand face of an injection well bore during MEOR or bioremediation processes. A first nutrient solution formulation supports growth of introduced microorganisms and a second nutrient solution formulation is used to promote biofilm formation to allow plugging of pores and channels in the subterranean target site, for MEOR or bioremediation.
    Type: Grant
    Filed: October 25, 2011
    Date of Patent: May 13, 2014
    Assignee: E I du Pont de Nemours and Company
