BioSqueeze's novel biomineralization technology provides the most effective solution for eliminating methane leaks in oil and gas wells, saving time and money otherwise spent on unsuccessful remediation attempts. BioSqueeze is the world leader in commercial biomineralization, utilizing natural soil bacteria delivered via low-viscosity, self diverting fluids to form calcium carbonate (limestone), steadily reducing permeability to create a permanent, gas-tight seal. Biomineralization is effective, environmentally friendly, and has a host of applications including leak sealing, enhanced oil recovery, soil stabilization, and infrastructure repair.
