APPLICATION

• recommended for installation in injection and production strings;
• for long-term stand-alone (without connection to the tubing) isolation of a production string interval which needs to be separated;
• for use in multiple-packer BHAs;

ADVANTAGES

• packers contain expandable supports to prevent rubber seal elements extrusion into annulus which increases the reliability of sealing and relieves packers unsetting;
• reliable long-term sealing of the production string as well as during the cyclic delivery of the injected fluid is ensured by the top mechanical anchor provided in the packer design unlike similar packers with the top hydraulic anchor;
• easy to release without additional tensile load;
• use of this packer allows to reduce as much as possible the non-production time and extend the well overhaul period as well as save materials, time and energy resources;
• packer design has been verified by many years of its successful application.

DESIGN FEATURES

• PRO-YADZH-O packer is mechanically set into the well by axial movements of the string (no tubing rotation required), it’s brought into its transit position by tensioning the string;
• PRO-YADZH packer is set into the well by ¼ right-hand rotation of the string with simultaneous downward movement and it is brought into its transit position by tensioning of the string;
• this equipment can be used multiply during one tripping operation;
• simple design and easy maintenance.
