Abstract:
Downhole tools including a wellbore isolation device that provides a plurality of components including a mandrel, a packer element, and a sealing ball, wherein the mandrel defines a central flow passage that allows fluid flow in at least one direction through the wellbore isolation device, wherein at least a portion of the mandrel is composed of a degradable metal material, at least a portion of the packer element is composed of an elastomer, and at least a portion of the sealing ball is composed of a degradable substance, and wherein the degradable metal material and the degradable substance degrades upon exposure to a wellbore environment.
