Abstract

An element is deployed within tubing extending to a downhole tool. The downhole tool includes a hydraulic tool and a valve coupled between the conveyance string and the hydraulic tool. The valve includes a valve seat having a passage directing the fluid from the conveyance string to the hydraulic tool. Deploying the element includes landing the element on the valve seat such that the element substantially obstructs flow of the fluid through the valve seat passage. The valve is opened to direct the flow of the fluid around the hydraulic tool, wherein opening the valve utilizes pressure generated in response to the element obstructing the flow of the fluid through the valve seat passage. At least a portion of at least one of the element and the valve seat is then degraded by an amount sufficient to permit the element to pass through the valve seat passage.
