ACCUJET

TOE INITIATION SLEEVE

Features

  • Differential pressure activation prevents premature opening during cementing operations.
  • Allows for calculation of reservoir pressure upon activation.
  • Large Bore ID.
  • Redundant activation mechanism.
  • Available in 500 psi (3.5 MPa) increments.
  • Does not require time delay for activation.
  • Atmospheric (absolute) pressure activation provides reliable opening pressure accuracy.
  • Greater flow area than burst port technology.
  • Compatible with industry wiper plugs.
  • Shift sleeve travels up to prevent unintended opening with wiper plugs.
  • Locking mechanism keeps the AccuJet Sleeve open once activated.
  • Optional ball seat configuration to pressure test liner.
  • All entry points open on activation.

Overview

Interra Energy’s AccuJet® Toe Initiation Sleeve is pressure activated via differential pressure burst disks. This ensures that the tool does not activate during cementing operations. The burst disks are designed and manufactured by Interra, providing rigorous quality control. This enables reliable opening pressure accuracy, making AccuJet one of the most reliable toe sleeves on the market.

The AccuJet Sleeve eliminates the use of coiled tubing or tubing-conveyed perforating for the first stage of fracturing operations. After establishing communication, the AccuJet Sleeve can also be used to stimulate the formation for the first treatment stage.

Operation

The AccuJet Sleeve is installed near the toe of the well as part of the casing string during the completion process. The tool can be run in a cemented or open hole completion.

Pressure is increased to the pre-calculated activation pressure, which immediately shifts the sleeve, opening 100% of the flow area for stimulation or pump down operations.

Application

  • Cemented and Open Hole
  • Compatible as the First Stage (Ball Drop, Coil Sleeve, P&P)
