1776 / TECHNOLOGY

Axial movement.
Radial engagement.

A wedge advances into a deformable receiver. The interaction converts axial movement into outward expansion toward the casing.

THE SEQUENCE

Movement with
a purpose.

The aluminum receiver is designed to undergo plastic deformation: a permanent change in geometry that supports continued engagement after setting.

  1. 01

    Initial position

    The plug, receiver, adapter, breakaway shaft and ball begin in their starting positions within the assembly.

  2. 02

    Axial movement

    The setting action draws the plug into the receiver.

  3. 03

    Receiver expansion

    The component interaction expands the receiver radially toward its set diameter and into engagement with the casing.

  4. 04

    Release sequence

    The illustrated arrangement allows the setting equipment to separate and the ball to move into its final position.

This explains the concept. Actual deployment requires an approved operating procedure.

INTEGRAL FEATURES

The receiver does
more of the work.

Radial expansion, casing engagement, mechanical anchoring and sealing are combined in the deformable receiver.

Sealing features

Raised sealing features are designed to conform against the inside surface of the casing during expansion.

Engagement surfaces

Integral wickered or textured regions are designed to resist axial movement under differential pressure and other downhole loading.

The described arrangement activates these features through deformation of the receiver itself, rather than a conventional separate slip assembly.
