TCO Tubing Disappearing Plug 2

The TDP-2 was developed from TCO's original TDP barrier plug, and features improved installation and remote cycling capabilities. The TDP-2 makes use of TCO's patented laminated glass material, built into an ISO 14310 V0 certified barrier plug package. This provides a total seal against all gases and fluids, even under extreme conditions.

The TDP-2 was developed from TCO's original TDP barrier plug, and features improved installation and remote cycling capabilities. The TDP-2 makes use of TCO's patented laminated glass material, built into an ISO 14310 V0 certified barrier plug package. This provides a total seal against all gases and fluids, even under extreme conditions.

As an option, the TDP-2 can be supplied with a Total Clean Environment Sub (TCES) debris extension system. The TCES is designed to provide an internal extension/bore for the pressure port communication with the trigger system.

TCO's patented laminated glass barrier material provides a secure, non-corrodible seal under high temperatures and axial loads, and is capable of withstanding extreme levels of differential pressure from both sides. The glass barrier disintegrates into silica upon removal.

Operational efficiency is improved through an internal removal system integrated into the plug housing, which is completely protected from the wellbore fluids. The optional TCES also drastically improves remote opening reliability in debris prone environments. This allows the TDP-2 trigger mechanism to function as intended, and to mitigate any debris or particles in the well. 

TCO is able to supply the TCES in lengths of 1 to 3 metres. Customized lengths may also be prepared upon request.

The TCES  was subjected to a series of verification tests upon release. All tests were conducted with an oil-based mud with a fluid weight of 1.60 SG, and the test set-up consisted of a standard TDP-2 and 2 metre TCES.  In addition to the built-in remote opening mechanism, a variety of removal options are available as a contingency. Full ID is always guaranteed after opening.
