Abstract:
Methods and compositions for a treatment fluid composition are disclosed for use within a subterranean formation, comprising: a degradable diverting agent, and a Schiff base comprising a degradation accelerator. The treatment fluid may be introduced into a formation and the Schiff base allowed to hydrolytically release the degradation accelerator, allowing the degradation accelerator to degrade the degradable diverting agent.
