DEVELOPING the Browse resources using floating liquefied natural gas (FLNG) technology is anticipated to create significant opportunities for Australia, Western Australia and the Kimberley region says Woodside’s senior vice president Browse, Steve Rogers.
The Browse joint venturers selected FLNG together with a subsea development as the preferred development concept for the Browse resources in September 2013, marking the start of the basis of design (BOD) phase.
The Browse FLNG development BOD reference case is based on three FLNG facilities and utilises Shell’s FLNG technology in conjunction with subsea technology drawing on Woodside’s offshore development expertise.
The development will include up to 57 subsea wells, 12 subsea manifolds, more than 190 kilometres of flowlines and 70 kilometres of umbilical cables which connect subsea equipment to the floating facilities.
“FLNG in conjunction with subsea technology provides a technically innovative solution to developing the remote, offshore Browse gas fields,” Mr Rogers said.
The Browse joint venturers have agreed a revised schedule to be in a position to enter front-end engineering and design (FEED) phase in mid-2015.
The Browse joint venture has finalised BOD technical activities and continues to progress key pre-FEED work.
Additional strategic activities will also be undertaken to further progress primary approvals, manage the impacts of the maritime boundary changes affecting the Browse retention leases and additional technical work to optimise and de-risk the development.
Drilling is scheduled to commence approximately two years after a final investment decision (FID) and operations are expected to extend for roughly 40 to 50 years.
The Browse FLNG development is estimated to deliver about $100 billion in government revenue and create substantial opportunities for WA and Australia during its operations.
The Browse joint venturers are committed to developing an integrated supply chain anchored in Western Australia, including infrastructure and services for receiving and transporting materials and equipment to and from the offshore FLNG facilities, and for personnel transport.
Perth and the West Kimberley area have been identified as the primary locations for the delivery of long-term support requirements.
Key features of the proposed supply chain include a primary support base for drilling and completions activities and a primary aviation support base (rotary-wing and fixed wing services), both in the West Kimberley.
It also includes north west regional support locations to support staging and transport of goods and/or personnel, and a primary production phase supply chain hub in Perth.
“We are continuing to work with governments, local communities and other relevant stakeholders to realise the potential opportunities across all phases of the proposed Browse FLNG development,” Mr Rogers said.
The Brecknock, Calliance and Torosa fields – known as the Browse resources – are estimated to contain gross contingent resources of 14.9 trillion cubic feet of dry gas and 441.2 million barrels of condensate.
The fields, located about 425 kilometres offshore north of Broome, lie in water depths varying between 350 metres and 700 metres.
Woodside is the operator of the Browse FLNG development on behalf of Woodside Browse, Shell Australia, BP Developments Australia, Japan Australia LNG (MIMI Browse) and PetroChina International Investment (Australia).
