Major Operator installed TCO's Q-Series Chemical Injection Devices at multiple nodes in lower completion and provided the Operator with a cost effective and reliable means of preventing halite build-up across the horizontal sand face over the life of the field.
With a track record of 600 glass plug installations worldwide and a reputation for innovation and robustness, TCO are supporting customers all over the world with easy to open glass barriers that provide full control of well operations.
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 patented Tubing Disappearing Plugs 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.
