Claim Text:
1. A method comprising: introducing a degradable ball into a wellbore penetrating a subterranean formation, wherein the degradable ball comprises an incompliant degradable polymer and a compliant filler material, the incompliant degradable polymer having an elastic modulus of about 2 GPa or greater, and the compliant filler material having an elastic modulus of less than about 2 GPa; seating the degradable ball in a baffle arranged within the wellbore, and thereby reducing a fluid flow through the baffle and defining an upper segment of the wellbore and a lower segment of the wellbore; treating the upper segment of the wellbore; and degrading the degradable ball and thereby returning fluid connectivity between the upper segment of the wellbore and the lower segment of the wellbore.
