Total E&P UK Limited has a high- pressure/high-temperature (HP/HT) gas condensate producer well in the North Sea with bottom hole temperatures of 380°F (193°C) and 30,000 psi. They completed it using 5-in tubing from surface to 17,543 ft (5,347 m).
A little over a decade later, the well developed casing and tubing integrity issues, causing several leaks across the annulus and the company killed it.
Within a few months, abandonment operations started retrieving the tubing from 14,436 ft (4,400 m) to surface with the intent of opening windows in the production casing and cementing to isolate the well.
