摘要： Systems and methods for bulk heating of a subsurface formation with at least a pair of electrode assemblies (50) in the subsurface formation (20) are disclosed. The method may include electrically powering the pair of electrode assemblies (50) to resistively heat a subsurface region between the pair of electrode assemblies with electrical current flowing through the subsurface region between the pair of electrode assemblies; flowing a shunt mitigator (64) into at least one of the pair of electrode assemblies; and mitigating a subsurface shunt between the pair of electrode assemblies with the shunt mitigator. Mitigating may be responsive to a shunt indicator that indicates a presence of the subsurface shunt.
