Abstract
Systems, methods and compositions for temporary sealing fractures in subterranean formations employ at least one constituent for temporary sealing a fracture in a subterranean well. The degradation kinetics of the composition is dependent upon at least one degradation temperature-time parameter for designating a temperature range and a time at which the composition degrades.
