TCO has installed and opened the first glass plug for ENI with great success. While this robust technology has been used in over 350 installations globally, this was the first time that a glass plug had been used by ENI. The glass plug was run in an upper completion in conjunction with perforation guns in the bottom of the completion string.
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.
