Well completion is the process of making a well ready for production after drilling. As in well drilling, seals used in well completion have to cope with the increasingly harsher conditions of deeper wells and diverse geographical areas, from the heat of Africa to the cold of Canada, Norway or Russia, with storage conditions as low as to -60℃. The system pressure can vary from 345 bar to 2070 bar, and the temperature can vary from -45 ℃ to 220 ℃. Seals in well completion applications have to deliver the required chemical compatibility, resistance to aggressive fluids and steam injection at very high temperatures of 315℃, as well as extended service life.
