Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. An actuation system comprising: a tubular having a passage; and an assembly disposed with the tubular, the assembly including a degradable restriction, the restriction only partially blocking the passage prior to being degraded, the degradable restriction forming a seat configured to receive a restrictor thereon to block fluid flow through the passage, the assembly configured to be actuated by creating a pressure differential across the restrictor to shift…
