On 24 April 2014 TCO successfully installed and opened the first Tubing Disappearing Plug (TDP-3-E) in a well with nitrogen filled tubing. Nitrogen-filled tubing complicates the process of cycling open a remotely pressure-operated plug, since the nitrogen's compressibility means that a huge volume of the gas is required in order to achieve the required fluctuations in pressure. Running the TCO TDP-3 in conjunction with an E-trigger provides a safe, reliable and cost-effective method of opening the barrier plug.
