DESCRIPTION APPLICATION

• recommended for multiply repeated well operations associated with generating pressure and fluid pumping with alternating pressure differential within one setting of the packer;
• for separation of formations during multiple-zone production and multiple-zone injection;
• for long-term autonomous (without connection to the tubing) isolation of the production string interval which needs to be separated;
• for installation into injection wells and for other long-term well operations with cyclic pressure differential across the packer.

ADVANTAGES

• packers contain expandable supports to prevent rubber seal elements extrusion into annulus which increases the reliability of sealing and relieves packers unsetting;
• ability to tension tubing up to 12 t after the packer is seated without breaking of the sealed separation of the production string intervals;
• reliable sealing of the production string for a long-term period as well as during the cyclic fluid supply, is achieved due to a top mechanical anchor provided in the packer design unlike other packers with similar functions that are provided with a top hydraulic anchor;
• easy packer releasing without additional tensile load.

DESIGN FEATURES

• PRO-YAT-O packer is mechanically set into the well by axial tubing movements (no tubing rotation is required) and brought into transit position by tensioning of the string;
• PRO-YAT packer is set into the well by one quarter right hand rotation of the string with set down motion, brought into transit position by tensioning of the string;
• this equipment can be used multiply for one round-trip operation;
• high repairability.
