Series 4800 Control Set High Expansion Packer

Also known as the “Patch thru a Patch”, the High Expansion Packer was designed to travel through an existing casing or tubing patch or other ID restriction(s) and set in a larger ID tubular below. This system incorporates a variation of TTS’ “fixed slip” system design to ensure each slip segment is separated, properly aligned with the packer axis, and evenly spaced around the packer body. Further design features of the slips and packer body allow for increased extension of the slip into larger diameters than previously possible.

Thru Tubing Systems is further pleased to introduce the Controlled Set System, another improvement to the Packer/Plug product line. The concept of this new feature is to have a control mechanism for sequentially setting each of the packer components. This ensures the elastomer is sufficiently energized prior to setting the lower slips. Precise, repeatable energizing of the packing element enables TTS to achieve a hydraulic seal from both directions.

The High Expansion Packer can be coupled with TTS’ Anchor Latch Seal Assembly and Polished Bore Receptacle to create a variable length straddle system capable of isolating intervals below restrictions and still provide relatively large flow area for zones below. This system can be installed via coiled tubing, electric line, or wireline.
