Name of the Project
Scarborough gasfield development.

Location
In the Carnarvon basin, about 375 km west-north-west of the Burrup Peninsula, in Western Australia.

Project Owner/s
The project is a joint venture (JV) between Woodside Petroleum and BHP. The JV partners Woodside and BHP reached an agreement in February this year to align their participating interests across the Scarborough and North Scarborough titles, resulting in Woodside’s holding a 73.5% interest and BHP holding the remaining 26.5% interest in both titles.

Project Description
Woodside is proposing to develop the Scarborough gas resource, which has a contingent resource of 11.1-trillion cubic feet and supports the recovery of more than 500-billion cubic feet per well.

The new offshore facilities will initially have seven high-rate, subsea gas wells tied back to a semisubmersible floating production unit moored in 900 m of water close to the Scarborough field.

Woodside’s preferred concept is to process Scarborough gas through a brownfield expansion of the existing Pluto liquefied natural gas (LNG) onshore facility.

Potential Job Creation
Not stated.

Capital Expenditure
Woodside recently flagged a 5% increase in the capital cost estimate for the Scarborough development, which is now estimated to require a $12-billion capital investment, comprising a $5.7-billion investment for the offshore component and a $6.3-billion investment for the onshore component.

Planned Start/End Date
First production from the Scarborough gasfield has been targeted for 2026.

Latest Developments
Woodside has been granted environmental approval for its Scarborough development.

Following an assessment by the state’s Environmental Protection Authority, Minister for Environment Amber-Jade Sanderson granted approval of the near-shore proposal, subject to a number of conditions.

The approval allows for the installation of a 32-km section of the Scarborough trunk line within state waters, along with associated activities required to construct the trunk line.

Extensive stakeholder consultation has been completed on the near-shore proposal, including a four-week public review of the draft dredging and spoil disposal management plan. Extraction and processing of the Scarborough field gas in Commonwealth waters was assessed separately under the Scarborough offshore project proposal, and was accepted by the National Offshore Petroleum Safety and Environmental Management Authority in March 2020.

Woodside is targeting a final investment decision for Scarborough in the second half of 2021.
