Wire Wrapped Rod Based Pre-Packed Screen
The primary application for this type of screen would be in unconsolidated formations where a gravel pack is economically undesirable, and its successful completion is in question. Variperm Pre-Packed Screens consist of an inner and outer wire wrapped screen packed with high quality smooth well rounded silica sand.
Pre-Packed Screens are available in many different sizes. Any of our Pipe Size or Telescope Screens can be used together to provide you with the best assembly that meets your requirements.
