Abstract:
Methods of servicing a wellbore and/or a subterranean formation including introducing a wellbore servicing fluid into the wellbore and/or the subterranean formation to degrade a degradable polymer therein by contacting the degradable polymer with a liquid neutralized degradation accelerator. The wellbore servicing fluid comprises a particulate salt degradation accelerator and a neutralizer activator. The particulate salt degradation accelerator is formed by reacting a degradation accelerator solution with an acid, the neutralizer activator is capable of dissociating the acid by neutralization from the particulate salt degradation accelerator so as to form the liquid neutralized degradation accelerator.
