Barossa Project

 ConocoPhillips and its co-venturers SK E&S Australia Pty Ltd and Santos Offshore Pty Ltd are proposing to develop discovered hydrocarbon resources located offshore about 300 kilometres north of Darwin, Northern Territory.

Barossa is an offshore gas and light condensate project that proposes to provide a new source of gas to the existing Darwin LNG facility, subject to suitable commercial arrangements being put in place.

In April 2018 Barossa entered the front-end engineering and design (FEED) phase of development which will continue for approximately 18 months.

During the FEED phase, the costs and technical definition for the Project will be finalised, gas and condensate sales agreements progressed and access arrangements negotiated with the owners of the DLNG facility and Bayu-Darwin Pipeline.

As Operator of the Barossa Project, ConocoPhillips believes Barossa is a leading candidate to backfill the Darwin LNG facility from 2023 when the existing offshore gas supply from Bayu-Undan is expected to be exhausted.

As DLNG Operator, ConocoPhillips also continues to progress discussions on other potential backfill options. The Barossa Project represents a further multi-billion-dollar investment that would help meet future global demand for natural gas and contribute significant income and employment opportunities. It would ensure ConocoPhillips continues to play a key role in building the economies of Darwin, the Northern Territory and Australia for many years to come.

The development concept includes a Floating Production Storage and Offloading (FPSO) facility, subsea production system, and a gas export pipeline, all located in Commonwealth waters.

The Barossa-Caldita assets are within the Bonaparte Basin, located in the Timor Sea. ConocoPhillips holds a 37.5% interest in permits NTRL5 and NTRL6, with co-venturers SK E&S (37.5%), and Santos (25%).

A 2015 appraisal drilling program saw three wells drilled in the NTRL5 permit area. Results from two of the appraisal wells were in line with expectations, with one well at the higher end of the expected range.

A new 3D seismic acquisition program was completed over both permits in 2016. A further two appraisal wells, Barossa-5 and Barossa-6, were drilled in NTRL5 in 2017. These results better inform us of the size and quality of the field. The data obtained from the appraisal program was integrated into subsurface models to support the FEED entry decision.

An Offshore Project Proposal (OPP) has been prepared by ConocoPhillips Australia Exploration Pty Ltd on behalf of its co-venturers in accordance with the Australian government’s environmental assessment process for a new petroleum project in Commonwealth waters. This process is regulated by the National Offshore Petroleum Safety and Environmental Management Authority (NOPSEMA). In July 2017 the Barossa OPP was published on NOPSEMA’s website for an eight-week public comment period to provide interested members of the public the opportunity to comment on the project during its early development stage.

Following the public comment period, the Barossa OPP was re-submitted to NOPSEMA after taking comments received into consideration. In March 2018, NOPSEMA formally accepted the Barossa OPP which has been published on the NOPSEMA website, and is also available to view below.

Acceptance of an OPP by NOPSEMA does not mean a project can proceed. Acceptance provides approval for the subsequent submission of separate Environment Plans (EPs) for project activities to NOPSEMA for assessment and acceptance. However, it does provide approval of the development concept design and key development assumptions that will be used to develop the EPs. Only after an EP has been accepted by NOPSEMA, can that activity commence.

The draft OPP that was published for public comment in July 2017 can be viewed on NOPSEMA’s website here.

ConocoPhillips understands the importance of conducting business in a manner that promotes economic growth in the communities and regions in which we operate. An approved Australian Industry Participation (AIP) Plan is now in place for the Upstream components of the Barossa Project, in compliance with requirements under the Australian Jobs Act 2013.

The Plan states how Barossa will provide “full, fair and reasonable opportunity” to Australian industry to supply goods and services to the project.

ConocoPhillips Australia has partnered with the Industry Capability Network NT to assist with Australian vendor identification and to raise awareness and communicate opportunities to provide goods and services to the project.

To register for potential opportunities please visit or contact Elena Tsangari, ICN Project Coordinator, at or 08 8992 9422.  Project supplier briefings were held in Perth on 31 July 2018, and Darwin on 2 August 2018. Links to these presentations are available within the ‘Additional Materials’ menu on the right hand side of this page.

A short video clip was filmed at the Perth supplier briefing which can be viewed Supplier briefing video or below.
