      Field Study.

AB  - A primary environmental risk from unconventional oil and gas development or 
      carbon sequestration is subsurface fluid leakage in the near wellbore 
      environment. A potential solution to remediate leakage pathways is to promote 
      microbially induced calcium carbonate precipitation (MICP) to plug fractures and 
      reduce permeability in porous materials. The advantage of microbially induced 
      calcium carbonate precipitation (MICP) over cement-based sealants is that the 
      solutions used to promote MICP are aqueous. MICP solutions have low viscosities 
      compared to cement, facilitating fluid transport into the formation. In this 
      study, MICP was promoted in a fractured sandstone layer within the Fayette 
      Sandstone Formation 340.8 m below ground surface using conventional oil field 
      subsurface fluid delivery technologies (packer and bailer). After 24 urea/calcium 
      solution and 6 microbial (Sporosarcina pasteurii) suspension injections, the 
      injectivity was decreased (flow rate decreased from 1.9 to 0.47 L/min) and a 
      reduction in the in-well pressure falloff (>30% before and 7% after treatment) 
      was observed. In addition, during refracturing an increase in the fracture 
      extension pressure was measured as compared to before MICP treatment. This study 
      suggests MICP is a promising tool for sealing subsurface fractures in the near 
      wellbore environment.
