Description

The ReAct™ Liner Shoe (RLS) is a well pressure control device that is designed to be installed below ReAct completion valves in the horizontal section of a well. It is deployed as part of the liner in the open position so that it can autofill the liner and enable pumping operations to be performed.

The RLS may be programmed to close upon the expiration of a predetermined ReAct time delay or, alternatively, by using ReAct pressure recognition technology. In addition, a combination of both the above methods may also be used.

Two robust, independent sets of ReAct electronic circuits and two independent operating mechanisms provide 100% redundancy. Once closed, the valve is mechanically locked in the closed position, creating a pressure barrier between the liner and the reservoir. This will allow multiple pressure tests to be carried out to test the completion, set the packer, and initiate the ReAct completion valves.

Features

  • Field-proven electronics
  • Delayed closing for up to 120 days
  • Field-proven, reliable technology
  • High pressure, high temperature (HPHT) compatible (165 °C)
  • Two independent electronic circuits
  • Two independent operating mechanisms
  • Protected sealing surfaces before activation
 

Benefits

  • Large flow area
  • Autofills the liner during deployment
  • Allows the liner to be pumped through
  • Eliminates the need for an inner work string
  • No intervention/manipulation required
  • Closes to provide pressure integrity after a predetermined time delay, pressure signal, or a combination of both
 

Applications

  • Remote barrier in horizontal wells
  • Provides ability to pump through liner during deployment
  • Holds pressure from above and below once activated
  • Enables upper completion packers to be set without the need for intervention
  • Enables pressure testing of upper completion
