Neptune submitted its draft decommissioning programs for the Juliet and Minke fields to the UK’s Department of Business, Energy and Industrial Strategy in late March 2019.

The documents contain the decommissioning programs for the Juliet field subsea installations and pipelines and Minke field subsea installations and pipelines.

The UK government announced the approval of the Juliet plan on Thursday, August 1, 2019.

The Juliet field is located in Block 47/14b of the UK Southern North Sea some 40km due east from the Humberside estuary and approximately 9km to the south of the Amethyst gas field. Juliet was discovered in December 2008 with well 47/14b-10 and subsequently developed by a two-well subsea tieback in a water depth of 55m to the Pickerill A facilities.

The Juliet field came into production in January 2014 from 47/14b-G1. The well 47/14b-G2 came into production in March 2014. Cessation of Production was submitted to the Oil and Gas Authority (OGA) in July 2018.

According to the plan, the Juliet manifold and wellhead protection structure will be fully recovered to shore for re-use/recycling. The trenched and buried pipeline and umbilical will be decommissioned in situ. Surface laid sections of pipeline and umbilical such as tie in spools and control jumpers will be recovered to shore for re-use/recycling. Exposed mattresses and grout bags will be recovered to shore for re-use/recycling. Wells will be plugged and abandoned.
