    摘要: A tool for forming a valve seat within a well that is capable of catching an obstruction will prevent flow of fluid downstream of the seat. The seat is formed by expanding a sleeve with a ring positioned around its periphery or as a subsequent step in the process. As the sleeve is expanded over the ring, the seat is formed. Once the seat is formed, an obstruction in the form of a ball or dart is dropped down to the seat. The sleeve acts as a stop for a secondary valve seat which catches the obstruction.

    摘要: A production sleeve assembly for use downhole includes a fluid pathway configured to provide fluid communication between an exterior of a wellbore tubular and an interior of the wellbore tubular through a chamber, a flow restriction disposed in the fluid pathway, and a valve disposed in series with the flow restriction in the fluid pathway. The valve comprises a rupture disk, and a plug releasably engaged in the chamber in series with the rupture disk. The valve is configured to allow production from the exterior of the wellbore tubular to the interior of the wellbore tubular through the chamber once the rupture disk is actuated, and the valve is configured to release the plug from the chamber when the rupture disk is actuated and the pressure within the exterior of the wellbore tubular is greater than the pressure within the interior of the wellbore tubular.
