Adams Pearson Associates Inc. and PanCanadian Petroleum Ltd. invite you to attend a Technology Information Session on Rod Based Wire Wrapped Screens (RBWWS).  pumpenboese Vent-screen is a German company specializing in the manufacturing of Rod Based Wire Wrap Screens (RBWWS).  Hauke Jeurgens from Vent-screen will discuss the equipment and suitable applications.

Background
Rod Based Wire Wrapped Screens have been successfully installed in steam injection oil wells and conventional, oil and gas, horizontal and multi-lateral wells (primarily onshore Europe and North Sea.  The unique screen design combines the high strength properties of the screen structure with a high inflow area and precision machined slot sizes.  

Effective sand control and stabilised borehole conditions are achieved by taking into account grain size distribution, reservoir characteristics and fluid characteristics.  Vent-Screen? guarantees precise slot dimensions and tight tolerances down to 50 micron (0.002”).  The screen can be used as a direct media to retain the reservoir formation, without any further assistance of gravel packs, prepacks or other sand control techniques.

APA are currently investigating the application of this technology in the SAGD wells - historically the screens have been more commonly used for sand control in North Sea multi-laterals or horizontal wells.

Summary of RBWWS Advantages

• reduced installation cost compared to pre-packs and gravel packs
• effective sand control
• reduced plugging risk and increased productivity
• higher reservoir drainage
• the well can be completed in drilling mud without plugging the sand control device
• use of stimulation fluids can be avoided
• easy installation due to flush, smooth liner surface and spiral bladed centralisers
• easy clean-up of the wellbore due to direct, non-obstructed inflow
