Patent attributes
A wellbore isolation device includes a wedge member that defines an outer surface and a barrel seal having a cylindrical body that provides an inner radial surface and an outer radial surface. The inner radial surface is engageable with the outer surface of the wedge member. The barrel seal further includes a plurality of longitudinally extending grooves defined through the body in an alternating configuration at opposing ends of the body. A raised lip protrudes radially from the outer radial surface and circuitously extends about a circumference of the body. A plurality of slip buttons is positioned in a corresponding plurality of holes defined in the outer radial surface of the body. At least one of the wedge member and the barrel seal is made of a degradable material that degrades when exposed to a wellbore environment.
