Annex Wellhead Platforms
Annex platforms are a cost-effective method of bringing near field discoveries into production by utilising shared production facilities.
Annex platforms provide the ability to:
Increase production from assets by adding new well slots
Add new facilities to existing assets
They offer advantages over slot recovery or subsea tiebacks as they:
are not reliant on old, potentially damaged infrastructure
do not require expensive subsea operations
can allow bigger modifications or additions to be installed
This concept can be highly advantageous on ageing platforms, where new wells or production facilities are required but no space is available.
