    摘要： A well screen assembly for use downhole comprises a fluid pathway configured to provide fluid communication between an exterior of a wellbore tubular and an interior of the wellbore tubular, a flow restrictor disposed in the fluid pathway, and a plug disposed in series with the flow restrictor in the fluid pathway. The plug substantially prevents a fluid flow through the fluid pathway. The plug is configured to be at least partially dissolvable when contacted by a fluid, and the fluid comprises a chemical configured to dissolve the plug.

    摘要： A technique facilitates a well operation employing at least one dehydration tube. The at least one dehydration tube is located along an exterior of a plurality of screen assemblies deployed in a wellbore and is fluidly coupled to a base pipe of at least one of the screen assemblies. The fluid coupling provides fluid access to the base pipe through a base pipe opening. Fluid flow along the at least one dehydration tube is controlled with a flow control mechanism. Additionally, an inflow of fluid from an exterior to an interior of select screen assemblies is separately controlled with an inflow control device associated with each select screen assembly.

    摘要： An apparatus for keeping a slotted tubular liner in axial alignment with a seamer head through which it is passing adjusts the spatial position of the seamer head in response to inputs from liner centerline sensors. The seamer head is mounted on a seamer head carrier that is vertically movable relative to a seamer head frame, which in turn is horizontally movable relative to a base structure. A programmable logic controller is programmed to continually poll the liner centerline sensors to determine the position of the seamer head relative to the liner, and to instruct vertical and horizontal axis positioners to move the seamer head as necessary to make the seamer head's rotational axis substantially coincident with the centerline of the liner as the liner passes through the seamer head.
