ESP Packers
70‐701 RWMB Hydraulic Set Multi‐Bore Packer

Product Overview


The RWMB is a high performance hydraulic set retrievable packer specifically designed to accommodate wire line retrieved and deployed electric submersible pump systems. A large main production bore allows ESP’s to be removed and installed independent of the packer and production tubing providing operators with significant cost savings while increasing safety and productivity. Additional bores provide feed through for electric cable penetrators, chemical injection, instrumentation or gas venting. Hydraulic activation enables reliable function of the packer where mechanical manipulation of the packer is not possible or practical such as in high angle well bores, or where the well head is to be flanged up prior to setting the packer. The RWMB is set by applying pressure to the tubing string and is released by applying tension to the tubing string. Releasing shear force is field adjustable prior to running to accommodate particular well conditions. The RWMB is extremely compact for ease of handling and deployment and is extremely simple and economical to service and re‐dress. The RWMB uses the fewest o‐rings of any competing product which means the fewest possible leak paths, resulting in the most secure and reliable packer available. Standard configuration includes materials which conform to NACE MR‐01‐75 for H2S service applications with differential pressure ratings of up to 3,000 psi *. The RWMB is also available in alternate materials and configurations for severe environments.
