CE CT Pump Out Choke
The CE CT Pump Out Choke Probe is run below the Hydraulic Knuckle Joint, in the Multi-Lateral Entry System. The Pump Out Choke Probe is generally sized so that the Hydraulic Knuckle Joint is prevented from fully articulating inside the main wellbore casing position. Once the lateral wellbore is effectively located, the Pump Out Choke Probe moves into the casing window position, allowing the Hydraulic Knuckle Joint to fully articulate. This action opens the bleed ports and provides a positive pressure signal as an indication that the lateral wellbore has been properly located.
A pinned piston sub acts as a choke to enable the activation of the hydraulic tool string. When the lateral has been successfully accessed, the choke sub can be over-pressured and pumped out into the probe body, which also acts as a catcher sub. Higher flow rates can then be pumped through the tool string for cleaning and stimulation operation applications.
