On 23 August 2012, GDF Suez opened their first remotely operated Tubing Disappearing Plug (TDP-2) from the Gjøa production platform, 3 km from the well location. This was the first time one of TCO's Tubing Disappearing Plugs with patented technology was opened from a production unit located a significant distance from the well.
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.
On 10 August 2014, a major operator used the TCO Tubing Disappearing Plug (TDP-3 HPHT) as a primary barrier against the reservoir, eliminating the costly use of high dencity clear completion fluid and saving the company an estimated USD 6 million.
