Abstract

An actuation system and method, the system including a tubular having a passage, and an assembly disposed with the tubular. The assembly includes a degradable restriction, the restriction only partially blocking the passage prior to being degraded. The assembly is configured to receive and prevent further movement of a restrictor through the tubular prior to the restriction being degraded. The assembly is further configured to release the restrictor when the restriction is degraded.
