The DTI Circulation Valve allows the circulation of fluid through the CT tool under normal operating conditions. By dropping a ball, this circulation path is closed off and fluid is diverted from the CT tool string to the well via flow ports.

The Circulation Valve Rupture Plug allows the circulation of fluid through the CT tool under normal operating conditions. By increasing CT pressure to a predetermined value, the rupture plug will blow out, thereby opening a flow path from the tool string to the well.

The DTI 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. Once the lateral wellbore is located the Pump Out Choke Probe moves into the casing window allowing the Hydraulic Knuckle Joint to fully articulate. This opens the bleed ports and provides a pressure signal that the lateral wellbore has been located.

The O.D. is usually specially sized to tubing drift or to pass through nipple restrictions. Large fluted flow paths are incorporated into the O.D. to maximise fluid by pass and shoulders are fully beveled to prevent tool string hang up.

The DTI CT Bow Spring Centraliser provides centralisation to CT tool string, whilst retaining the ability to pass through smaller tubing restrictions. The bow springs can either be incorporated as a conventional tool or slipped over the tool string on carriers and locked in place with set screws. The bow springs are replaceable and easily changed out without the need to remove any tool from the tool string.

The DTI Venturi Junk Basket is used to collect downhole debris and retain it in the tool. Circulating flow creates a suction effect within the tool which draws debris up inside the junk basket. Inside the tool a metal filter screen, magnets and a flapper junk shoe retain debris in place so it can be removed from the well.
