15-151 RD7 Mechanical Set Double Grip Packer

Product Overview


The RD7 Packer is a mechanical set double grip single string retrievable packer designed for applications where an economical solution to zonal isolation, injection, pumping and production operations is required. The RD7 is set by simply rotating the tubing ¼ turn and is released by rotating the packer a further ¼ turn. The field proven upper slip releasing system ensures reliable release at low forces under all conditions. An integral by-pass valve reduces surge effect during run in, ensures tubing to annulus pressure is balanced during release and minimizes swabbing effect during retrieval of the packer. The RD7 may be packed off with tubing compression or tension making it an ideal choice for both deep and shallow applications. Once set the packer may be left in compression, neutral or tension and is unaffected by pressure or tubing movement. The RD7 is extremely compact for ease of handling and deployment and is extremely simple and economical to service and re-dress. When used in combination with an RPV bridge plug valve the packer becomes a versatile multi-set retrievable bridge plug. Standard configuration includes materials which conform to NACE MR-01-75 for H2S service applications with differential pressure ratings of up to 7,500 psi *. The RD7 is available in alternate materials, elastomers and configurations for severe environments. A full line of accessory equipment is available such as on/off seal connectors, expansion joints, bridge plug valves and flow control equipment.
