<h1>Julimar-Brunello Gas Project,Western Australia,Australia</h1>
<p>The Julimar-Brunello Gas Project is an operating offshore gas project in Western Australia,Australia,operated by Woodside Petroleum. It is a conventional gas development in the Carnarvon Basin and supplies gas and condensate into the broader Wheatstone LNG and domestic gas system. The project covers the Julimar and Brunello fields in permit areas WA-356-P and WA-49-L. Woodside and KUFPEC are the core joint venture participants. A 2024 Woodside-Chevron asset swap agreement is expected to transfer Woodside’s interest to Chevron after conditions are met. The project is a producing upstream asset with continuing development through Julimar-Brunello Phase 3.</p>

<h2>Location and Basin</h2>
<p>The project is offshore Western Australia in the Carnarvon Basin,approximately 200 km northwest of Western Australia and about 48 km from the Montebello Islands. Permit areas include WA-356-P and WA-49-L. The basin hosts major LNG-linked offshore developments such as the North West Shelf,Pluto,and Wheatstone. Julimar-Brunello is tied to established offshore and onshore gas processing infrastructure rather than a standalone development.</p>
<h2>Ownership and Operatorship</h2>
<p>Woodside Petroleum operates the project with a 65% interest; KUFPEC holds 35%. Parent companies are Woodside Energy Group Ltd and Kuwait Petroleum Corporation. In December 2024,Woodside and Chevron announced an asset swap under which Woodside would transfer its 65% operated interest in Julimar-Brunello to Chevron,along with its 13% non-operated interest in Wheatstone,in exchange for Chevron’s interests in the North West Shelf Project,North West Shelf Oil Project,and Angel CCS Project,plus a cash payment of up to USD 400 million. Until the transaction closes,Woodside remains operator; Chevron is the expected incoming owner.</p>

<h2>Infrastructure and Facilities</h2>
<p>The project includes the existing Julimar Field Production System with subsea tiebacks to the Wheatstone platform. Gas and condensate from Julimar and Brunello fields are partially processed offshore before delivery to the Wheatstone LNG and domestic gas facilities. Julimar-Brunello Phase 3 involves up to four development wells tied back from the Julimar field to the existing production system,plus one well in the Penfolds prospect,with subsea installation in water depths of approximately 120 m to 210 m.</p>
<h2>Production and Reserves</h2>
<p>The project supplies gas and condensate into the Wheatstone system. A 2014 Woodside presentation reported 2P reserves of 279 MMboe,but this is historical and should not be taken as current. Wheatstone LNG Trains 1 and 2 started in 2017 and 2018,and domestic gas production began in 2019. Current field-level production rates are not fixed and depend on reservoir performance,well availability,and system integration. Phase 3 is designed to sustain or enhance field recovery.</p>
<h2>Recent Developments</h2>
<p>The most significant recent event was the Phase 3 final investment decision in April 2023 by the Julimar-Brunello Joint Venture. NOPSEMA approved drilling and subsea installation plans for Phase 3. In December 2024,Woodside and Chevron announced the asset swap that would transfer Woodside’s interest to Chevron,with Chevron expected to take ownership from mid-2026 subject to conditions. A 2025 Western Australian domestic gas statement noted subsea construction for Phase 3 during the first half of 2025.</p>
