Barossa is an offshore gas and light condensate project being progressed by the Barossa Joint Venture comprising ConocoPhillips Australia Exploration Pty Ltd as Operator (ConocoPhillips Australia), Santos Offshore Pty Ltd and SK E&S Australia Pty Ltd.
The project proposes to provide a new source of gas to the existing Darwin LNG facility, subject to suitable commercial arrangements being put in place. It would backfill the facility from 2023 when the existing offshore gas supply from the Bayu-Undan offshore field is expected to be exhausted.
Development of the large discovered Barossa resource will extend the operating life of the existing DLNG facility for 20-plus years, thereby continuing to help meet future global demand for natural gas and contributing significant income and employment opportunities for Australia.
The offshore development area is located within Commonwealth waters of the Bonaparte Basin, about 300 km north of Darwin, Northern Territory. The area encompasses petroleum retention lease NT/RL5 and potential future phased development in the smaller Caldita Field to the south in petroleum retention lease NT/RL6. ConocoPhillips holds a 37.5% interest in permits NTRL5 and NTRL6, SK E&S (37.5%) and Santos (25%).
In April 2018 Barossa entered the front-end engineering and design (FEED) phase of development. During this phase, the costs and technical definition will be finalised, gas and condensate sales agreements progressed and access arrangements negotiated with the owners of the DLNG facility and Bayu-Darwin Pipeline.
The project development concept includes a Floating Production Storage and Offloading (FPSO) facility, subsea production system, supporting in-field subsea infrastructure and a gas export pipeline. The FPSO facility will separate the natural gas and condensate extracted from the field with the dry gas transported via the export pipeline for onshore processing. The condensate will be exported directly from the FPSO to offtake tankers.
The proposed new gas export pipeline will be 260-290 km long and would connect to the existing Bayu-Undan to Darwin pipeline in Commonwealth waters, subject to agreed commercial arrangements. The export pipeline route is still subject to refinement and therefore a pipeline corridor has been identified to allow flexibility at this early stage in the design phase.
The procurement approach for major scopes, such as the FPSO, Subsea, Export Pipeline and Drilling, will be through a combination of Engineering, Procurement and Construction/Installation (EPC/I), leasing or direct contracting and procurement by ConocoPhillips Australia.
Design of the facilities will be undertaken in accordance with the Project’s design basis and include Company standards and specifications, Australian, ISO and other international standards and codes, including those broadly adopted in the Australian oil and gas industry and in line with local industry practice.
Limited procurement activity is expected during FEED with most expected to occur post-FID. Supplier/Industry briefings will be conducted in Darwin and Perth as part of the Australian Industry Participation (AIP) Plan for the Project, approved by the Commonwealth Government. The briefings will raise awareness of the Project and communicate opportunities to Australian entities to supply key goods and services.
