Challenge
Within the design of conventional burst ports, once one port is activated, pressure can travel outside the port and equalize, preventing other ports from opening.
Solution
Interra Energy challenged itself to create a new toe sleeve that incorporated the proven accuracy of burst discs, while guaranteeing 100% opening of the flow area. This reduced the limitations that were commonly seen with burst ports while injecting into the toe.
Results
The AccuJet toe initiation sleeve design, released by Interra Energy in 2013, uses multiple burst discs that only require one to be activated. This allows a sleeve to shift exposing all of the injection windows to the formation.
As of June 2020, there have been over 16,000 successful deployments of the AccuJet’s technology in such formations as the Viking, Montney, Cardium, Duvernay, Permian, Bakken, Haynesville and the Eagle Ford.
