Inter Remote Bypass Valve (IRBV)

The IRBV is a completion string integrated barrier valve, with a control line bypass feature. The design is based on the field proven Inter Remote Shatter Valve (IRSV) glass plug technology. The barrier valve operates with three positions: open, closed and then permanently open.

The IRBV is installed with the bypass ports in open position. This ensures standard completion activities can be conducted and the operator would still be able to accomplish bull heading in the event of a well control situation. It is activated to closed and open position by subjecting the tool. The valve is shifted to closed position after a predefined number of tubing pressure cycles have acted on the system. Once the bypass is closed an ISO14310 V0 well bidirectional barrier is established. The barrier element is shattered by subjected the tool to a predefined number of pressure cycles. The valve then activates to its final open state, resulting in full bore ID through the assembly for production and future intervention.

The tool can be utilized in various applications, such as;

  • A shallow barrier for BOP removal and VXT installation purposes, for both conventional and subsea completion.
  • As a deep barrier allowing for communication down the tubing until the valve is closed. I.e. to avoid running upper completion closed ended or allowing for communication when e.g. running standalone screens.

By utilizing the IRBV, the drilling rig can batch complete subsea wells and, at a later stage, batch install the vertical x-mas trees (VXT)  with an Inspection Maintenance and Repair (IMR) vessel. This ensures wireline (WL) intervention can be avoided during the completion installation.
