_{One method of open hole completion is to use a Production Screen for
sand control. Several types of screen are used, from a simple single
wrap screen (Brage), to more sophisticated types, such as Prepack resin

During the initial phase of production, the drilling fluid remaining in the

extremely important that the drilling fluid must not plug the screen when
production starts.}

The Production Screen Tester is used in the field or laboratory to ensure
that a drilling fluid will flow through a completion
