CP-Wrap (Wire Wrap Well Screens)

Wire Wrap Well Screens have been used for over 60 years for sand control in Oil wells and are still commonly used today. CP-Wrap can be used in both Gravel Pack and Stand Alone Screen (direct retention) applications.

 

With gravel pack applications, the Wire Wrap Screen is commonly used in cased hole gravel packs to retain the pumped gravel. For high rate water packs (HWRP) and Frac Pack applications a more robust version of CP-Wrap incorporating a heavy duty wire is available.

 

For Stand Alone Screen (Direct Retention) applications, the screen is designed to retain the formation sand and maintain an open well bore. With good Particle Size Distribution (PSD) data and the addition of laboratory testing for optimising slot selection, CP-Wrap can be used for uniform sand formations (D40/D50 ≤ 2.5) with a D50 greater than 125µm. (Dependant on additional well information).
