PFT’s field-attachable CaymanTM Fail-Safe* Penetrator represents an advance in safety with benefits to both field operators and the environment. The penetrator is equipped with a mechanical means of retention within the tubing hanger, as well as a mechanism to allow the ESP cable to pull away under a prescribed load. In the event of a downhole failure of the production tubing, seal barriers remain in place and well control is maintained. Comparable systems currently in use offer no means of retention. In the event of a tubing failure the entire penetrator will be pulled from the tubing hanger, leaving an open pathway for wellbore fluids to escape to the atmosphere. Such circumstances may jeopardize public safety, as well as damage the surrounding environment.
