摘要
A sand control screen assembly includes a base pipe having an interior and defining one or more flow ports. At least one sand screen is arranged about the exterior of the base pipe and has a predetermined screen gauge. At least one dead space is axially offset from the at least one sand screen and comprises at least one of an axial length of the base pipe and a shroud arranged about an exterior of the base pipe and extending axially from the at least one sand screen. One or more perforations are provided at the at least one dead space and are defined through at least one of the axial length of the base pipe and the shroud. Each perforation defines an opening and an erosion-resistant material deposited at the opening. A size of the opening is equal to or smaller than the predetermined screen gauge.
