The Sable Offshore Energy Project, which has been producing natural gas and liquids since December 1999, has shut as planned. The project, operated by ExxonMobil, consists of seven offshore platforms and 340 kilometres of subsea pipeline. According to ExxonMobil, December 31, 2018 marked the end of production.

Decommissioning of the project has been underway since 2017. According to the decommissioning timeline, all wells will be permanently sealed by early 2020. Offshore platforms will be removed by the end of 2020.

Offshore and onshore pipelines will be flushed to remove hydrocarbons. Offshore pipelines will then be filled with water and left in place unless they pose a hazard to marine life or other users of the environment. Onshore pipelines will also be left in place. Aboveground structures will be removed and onshore plants will be dismantled.

Full decommissioning is scheduled to be completed in 2021.
