The key objective of this project is to bring the Laminaria-5 well back into production to extend the economic life of the Laminaria field. This is to be achieved by changing out the subsea tree (SST), the assembly of valves on top of the wellhead). An attempt was made in 2012 to replace the SST by the former titleholder, Woodside. At that time, due to a suspected Tubing Retrievable Subsea Safety Valve (TRSSV) failure and inability to recover the downhole tool, a 7.2 m long tool string and approximately 75 m of wire was cut and left down hole. Due to a suspected issue with the TRSSV flapper and the tooling required to repair the well not being available, Woodside decided to leave the well temporarily abandoned. The current program aims to restore flow to the well. The project is scheduled to be undertaken in 2018, ideally in the first quarter (Q1) of 2018, subject to MODU availability and other variables such as weather conditions. It is anticipated that the project will take up to 30 days to complete.
