Shell Australia is proposing to develop the Crux gas field, approximately 190 km off the Kimberley coast of Western Australia and 620 km north-east of Broome.
The Crux project will be developed to supply backfill gas (LNG, LPG and Condensate) to the Prelude Floating Liquefied Natural Gas (Prelude FLNG) facility. The project consists of a not normally manned (NNM) platform with five production wells, in ocean waters approximately 165 m deep. The facility will be connected to Prelude via a 165 km export pipeline.
Crux will be operated remotely from the Prelude FLNG facility.
Project Concept Graphic
The frontend engineering design (FEED) process has commenced and a final investment decision (FID) on whether to proceed is anticipated in 2020. Crux is expected to have at least a 20-year lifespan. Future investment decisions could extend the life of the project.
Crux Project development timeline
Completion of the Offshore Project Proposal review process and public comment period. Front End Engineering Design has commenced.
The Final Investment Decision is expected in 2020.
Foundation development drilling is expected to commence in 2021. Several key components will be constructed offsite and transported to location. The Crux platform will then be installed and the export pipeline between the Prelude FLNG facility and Crux will be installed and commissioned.
Start-up is expected to take place approximately 5 years after the Final Investment Decision. There will be ongoing operations, surveillance and maintenance throughout the life of the project (which is at least 20-years).
At the end of the project (approximately 20 years) the well will be abandoned, and the platform, subsea facilities and export pipeline will be decommissioned.

About the OPP
Crux is an offshore project which requires Government approval. Shell has developed the Offshore Project Proposal (OPP), which has been submitted to the National Offshore Petroleum Safety and Environmental Management Authority (NOPSEMA) as part of the first stage of the approval process.
