Woodside Releases First Quarter Report for Period Ended 31 March 2025

Outstanding performance from high quality assets

Operations

• Maintained exceptional production from Sangomar of 78 Mbbl/day (Woodside equity interest) produced in the quarter.
• Quarterly production of 49.1 MMboe (546 Mboe/day), down 4% from Q4 2024 due to weather impacts at NWS and unplanned outages at Pluto, partially offset by higher production at Shenzi and Atlantis. Quarterly production increased 9% from Q1 2024 due to the addition of Sangomar production.
• Quarterly revenue of $3,315 million, down 5% from Q4 2024 primarily due to lower production and lower oil-linked prices. Quarterly revenue increased 13% from Q1 2024 due to Sangomar start-up in July 2024 and high gas hub-linked prices.
• Sold 25.4% of produced LNG at prices linked to gas hub indices in the quarter (9.4% of total equity production).

Projects

• Strong project execution for the quarter, with all projects on schedule and budget.
• The Beaumont New Ammonia Project was 90% complete, with Phase 1 of the project on track for startup in the second half of 2025.
• The Scarborough Energy Project was 82% complete, and remains on track for first LNG cargo in the second half of 2026.
• The Trion Project was 26% complete, and remains on track for first oil in 2028.

Portfolio developments

• Further streamlining Woodside's portfolio and generating near-term cash flow by divesting the Greater Angostura assets.¹
• Subsequent to the quarter, entered an agreement for the sale of a 40% interest in Louisiana LNG Infrastructure LLC.²
• Subsequent to the quarter, signed LNG sale and purchase agreements with Uniper for the supply of up to two million tonnes per annum.³ 

Woodside Energy Group (ASX: WDS) (NYSE:WDS):

Woodside CEO Meg O'Neill said the company continued its focus on operational excellence and project delivery over the first quarter of 2025, while laying the foundation for Woodside's next phase of value creation.

"We maintained world-class operational performance across our portfolio of high-quality assets, with Sangomar further boosting quarterly revenue through exceptional production of 78 thousand barrels per day at almost 98% reliability.

"Significant progress was made on our major growth projects, all of which are proceeding to schedule and within budget.

"At our Beaumont New Ammonia Project, pre-commissioning activities are expected to commence in the second quarter, with startup targeted for the second half of the year. This value-creating opportunity is set to deliver returns above our capital allocation framework and will position Woodside very competitively in the growing market for lower-carbon ammonia.

"Our Scarborough Energy Project is progressing as scheduled towards first LNG cargo in the second half of 2026, with the hull and topsides of the floating production unit being prepared for integration activities.

"The Trion Project is also gaining momentum. The construction of the subsea equipment and floating facilities is progressing well, and the project remains on schedule for first oil in 2028.

"We are progressing at pace towards a final investment decision on Louisiana LNG, positioning Woodside as a global LNG powerhouse. We passed a major milestone on 7 April, announcing the sale of a 40% interest in the infrastructure entity to Stonepeak, a leading global investment firm. The accelerated capital contribution from Stonepeak enhances Louisiana LNG returns, reduces Woodside's capital commitments and strengthens Woodside's near-term capacity for shareholder distributions.

"The exceptional value proposition offered by Louisiana LNG was further demonstrated by our 17 April agreement for long-term supply of LNG to Uniper, whose leadership in European energy markets make it an ideal foundation customer for the project.

"We are pleased with the strong level of interest from potential strategic partners and are advancing discussions targeting further equity sell-down in Louisiana LNG.

"Louisiana LNG has a Foreign-Trade Zone, enabling the project to defer payment of tariffs until completion of each LNG train. We are assessing the potential impacts of recent tariff announcements and potential further trade measures on Louisiana LNG. Around 25% of Louisiana LNG's estimated capital expenditure is equipment and materials, approximately half of which is currently expected to be sourced from the US.

"As Australia approaches a federal election, it is encouraging to see both major parties recognising the essential role of gas in supporting national prosperity and a stable energy transition. We look forward to certainty for ongoing operations at the North West Shelf beyond 2030, to enable it to support thousands of direct and indirect jobs, billions of dollars in taxes and royalties, and secure future gas supply to Western Australia.

"Customer demand for Woodside's LNG remains robust. The 15-year sale and purchase agreement with China Resources announced during the quarter was Woodside's fourth new long-term contract with a regional customer in just over a year.

"With significant growth in the pipeline, we continue to streamline our business to focus on core and high-value assets. Our agreement to divest the Greater Angostura assets in Trinidad and Tobago for $206 million underscores our disciplined approach to portfolio management and optimisation. We applied the same discipline in declining to progress Namibian Petroleum Exploration Licence 87, exiting H2TAS and reassessing the H2OK project."

Pluto LNG

• LNG reliability was 89.9% for the quarter due to the impact of three unplanned train outages, which were rectified within days of each event. Facility performance continues to be proactively monitored to minimise the risk of future unplanned outages.
• Completed maintenance activities during facility downtime to minimise future planned outages.
• Successfully processed additional volumes through the Pluto-KGP Interconnector, using capacity at the North West Shelf.

North West Shelf (NWS) Project

• Achieved strong quarterly LNG reliability of 96.5%.
• Received approvals from the North West Shelf Joint Venture for long lead items on the Greater Western Flank Phase 4 Project, a five-well subsea tie-back to existing NWS offshore facilities. The project will support the delivery of domestic gas into the WA market during a forecasted shortfall in supply post-2028, with a final investment decision (FID) planned for the second half of 2025.
• Successfully completed remote operations of offshore assets during a significant cyclone event, which limited the impact on production.
• Continued LNG Train 2 permanent retirement activities following cessation of production in Q4 2024, with retirement work scopes being undertaken in a phased manner.

Bass Strait

• Woodside approved investment in the Kipper 1B Project and the Turrum Phase 3 Project. Through the development of these projects, Woodside is expected to add more than 100 petajoules (Woodside equity interest) to the south-eastern Australian domestic gas market, supplying local manufacturers, power generators, and homes.
• The Kipper 1B Project is expected to expand capacity from the Kipper field and deliver gas supplies ahead of winter 2026 through the drilling of a subsea well and upgrades to the West Tuna platform.
• The Turrum Phase 3 Project is expected to deliver much-needed gas to south-eastern Australia by 2027 from a five-well infill development of the Turrum and North Turrum fields and topsides modifications to the Marlin B platform. Once the project comes online, it will produce four times more gas than Queensland supplied to the southern states in 2024.

Sangomar

• Achieved exceptional production of 99 thousand barrels per day (Mbbl/d) (100% basis, 78 Mbbl/d Woodside share) at 97.6% reliability, with production from the Sangomar field remaining at plateau for the quarter.
• During the quarter, based on a positive response observed in S400 oil producers from water injection, contingent resources were migrated to developed reserves. The reserve addition was 7.1 million barrels to proved (1P) reserves and 16.1 million barrels to proved plus probable (2P) reserves, Woodside share.⁹ As a result, Woodside expects Sangomar's depreciation, depletion and amortisation (DD&A) rate for 2025 to decrease by 5 to 10% from its 2024 DD&A rate of approximately $56/boe.
• Cargoes were delivered to China, Europe, US and Senegal's domestic refinery.

United States of America

• Achieved outstanding reliability of 99.8% at Shenzi.
• Strong quarterly production at Shenzi was supported by a well returning to production in late 2024 and ongoing optimisation efforts.
• Completed planned well intervention campaigns at Atlantis and commenced execution of an infill sidetrack producer.
• Strong quarterly production from the Mad Dog field, Argos facility, with uplift seen from riser gas lift.

• Subsequent to the quarter, Woodside signed LNG sale and purchase agreements with Uniper for the supply of 1.0 million tonnes per annum (Mtpa) from Louisiana LNG LLC for up to 13 years from the commercial operations date (COD) of Louisiana LNG and up to 1.0 Mtpa from its global portfolio commencing with Louisiana LNG's COD over a term until 2039.¹⁰
• Signed a long-term sale and purchase agreement with China Resources Gas International Limited for supply of approximately 0.6 million tonnes of LNG per year over 15 years on a delivered basis, commencing in 2027.
• Supplied 25.4% of produced LNG at prices linked to gas hub indices, realising a 23% premium compared to oil-linked pricing. This represents 9.4% of Woodside's total equity production. Full-year guidance remains unchanged at 28-35% of produced LNG.
• Executed incremental Western Australian gas sales of 3.6 PJ for delivery in 2025 and 2026. Woodside continues to engage with the Western Australian domestic market on additional supply requirements for 2025, 2026 and 2027.
• Delivered 526 TJ of trucked LNG, equivalent to 513 trailers, to customers in northern Western Australia.
• Progressed preparations to release an expression of interest before 30 April 2025 for Australia east coast natural gas supply to ensure compliance with the terms of Woodside's Conditional Ministerial Exemption under the Gas Market Code.

Greater Angostura assets divestment

• Woodside entered into an agreement in March 2025 with Perenco to divest its Greater Angostura assets in Trinidad and Tobago for $206 million. The divestment is inclusive of Woodside's interest in the shallow water Angostura and Ruby offshore oil and gas fields, associated production facilities and onshore terminal. The transaction provides near-term cash flow to support ongoing investments and shareholder distributions and builds on the Australian asset swap announced in December 2024, further streamlining Woodside's portfolio.¹⁵ The transaction is expected to close in Q3 2025, with an effective date of 1 January 2025. Completion of the transaction is subject to conditions precedent.

Climate and sustainability

• Woodside held a Sustainability Briefing on 3 April 2025, part of a structured program of engagement with investors on the company's approach to climate and other sustainability topics. The briefing was held following the release of Woodside's Sustainability disclosures in February 2025.
• Woodside awarded a A$35 million contract to Cherratta Lodge, a Traditional Owner operated business in Karratha, Western Australia, for provision of accommodation to the workforce for Pluto Train 1 modifications. This is the first time Woodside has awarded a village accommodation contract to a Traditional Owner business and is part of the significant local economic benefits arising from the project.

Hedging

• Of the 30 MMboe of 2025 oil production previously hedged at an average price of approximately $78.7 per barrel, approximately 25% was delivered by the end of the quarter.
• Woodside also has a hedging program for Corpus Christi LNG volumes designed to protect against downside pricing risk. These hedges are Henry Hub (HH) and Title Transfer Facility (TTF) commodity swaps. Approximately 95% of 2025 and 87% of 2026 volumes have been hedged.
• The realised value of all hedged positions for the quarter ended 31 March 2025 is a pre-tax profit of approximately $14 million, with a $32 million profit related to oil price hedges offset by a $23 million loss related to Corpus Christi hedges, and a $5 million profit related to other hedge positions. Hedging profit will be included in "other income" in the full-year financial statements.

Funding and liquidity

• In the quarter, Woodside:
  • Entered into two $1,500 million short term liquidity facilities.
  • Repaid a $1,000 million bond that matured during the quarter.
  • Drew $800 million from available liquidity debt facilities.
• Following the payment of the 2024 final dividend on 2 April 2025, Woodside had liquidity of $7,300 million.

Embedded commodity derivative

• In 2023, Woodside entered into a revised long-term gas sale and purchase contract with Perdaman. The contract was assessed to contain an embedded commodity derivative, where a component of the selling price is linked to the price of urea. For the quarter ended 31 March 2025, an unrealised gain of $17 million has been recognised through other income. The fair value of the Perdaman embedded derivative has been estimated using a Monte Carlo simulation model. The valuation approach is currently under review for improvement opportunities.

Notes to petroleum reserves and resources

1. The petroleum resource estimates are quoted as at the effective date of 31 March 2025, net Woodside share. For details of Woodside's year end 2024 reserves position, see the Reserves and Resources Statement included in the 2024 Annual Report.
2. All numbers are internal estimates produced by Woodside. Estimates of reserves and contingent resources should be regarded only as estimates that may change over time as additional information becomes available.
3. The reference point is defined as the outlet of the floating production storage and offloading facility (FPSO).
4. ‘Reserves' are estimated quantities of petroleum that have been demonstrated to be producible from known accumulations in which the company has a material interest from a given date forward, at commercial rates, under presently anticipated production methods, operating conditions, prices, and costs. Woodside reports reserves inclusive of all fuel consumed in operations. Woodside estimates and reports its proved reserves in accordance with SEC regulations which are also compliant with the 2018 Society of Petroleum Engineers (SPE)/World Petroleum Council (WPC)/American Association of Petroleum Geologists (AAPG)/Society of Petroleum Evaluation Engineers (SPEE) Petroleum Resources Management System (PRMS) (SPE-PRMS) guidelines. SEC-compliant proved reserves estimates use a more restrictive, rules-based approach and are generally lower than estimates prepared solely in accordance with SPE-PRMS guidelines due to, among other things, the requirement to use commodity prices based on the average of first of month prices during the 12-month period in the reporting company's fiscal year. Woodside estimates and reports its proved plus probable reserves in accordance with SPE-PRMS guidelines which are not compliant with SEC regulations.
5. Assessment of the economic value in support of an SPE-PRMS (2018) reserves and resources classification, uses Woodside Portfolio Economic Assumptions (Woodside PEAs). The Woodside PEAs are reviewed on an annual basis, or more often if required. The review is based on historical data and forecast estimates for economic variables such as product prices and exchange rates. The Woodside PEAs are approved by the Woodside Board. Specific contractual arrangements for individual projects are also taken into account.
6. Woodside uses both deterministic and probabilistic methods for the estimation of reserves and contingent resources at the field and project levels. All proved reserves estimates have been estimated using deterministic methods and reported on a net interest basis in accordance with the SEC regulations and have been determined in accordance with SEC Rule 4-10(a) of Regulation S-X.
7. ‘MMboe' means millions (10⁶) of barrels of oil equivalent. Natural gas volumes are converted to oil equivalent volumes via a constant conversion factor, which for Woodside is 5.7 Bcf of dry gas per 1 MMboe. All volumes are reported at standard oilfield conditions of 14.696 psi (101.325 kPa) and 60 degrees Fahrenheit (15.56 degrees Celsius).
8. ‘Proved reserves' are those quantities of crude oil, condensate, natural gas and NGLs that, by analysis of geoscience and engineering data, can be estimated with reasonable certainty to be economically producible from a given date forward from known reservoirs and under existing economic conditions, operating methods, operating contracts, and government regulations. Proved reserves are estimated and reported on a net interest basis in accordance with the SEC regulations and have been determined in accordance with SEC Rule 4-10(a) of Regulation S-X.
9. ‘Undeveloped reserves' are those reserves for which wells and facilities have not been installed or executed but are expected to be recovered through future significant investments.
10. ‘Probable reserves' are those reserves which analysis of geological and engineering data suggests are more likely than not to be recoverable. Proved plus probable reserves represent the best estimate of recoverable quantities. Where probabilistic methods are used, there is at least a 50% probability that the actual quantities recovered will equal or exceed the sum of estimated proved plus probable reserves. Proved plus probable reserves are estimated and reported in accordance with SPE-PRMS guidelines and are not compliant with SEC regulations.
11. The estimates of petroleum reserves and contingent resources are based on and fairly represent information and supporting documentation prepared by, or under the supervision of, Mr Benjamin Ziker, Woodside's Vice President Reserves and Subsurface, who is a full-time employee of the company and a member of the Society of Petroleum Engineers. The reserves and resources estimates included in this announcement are issued with the prior written consent of Mr Ziker. Mr Ziker's qualifications include a Bachelor of Science (Chemical Engineering) from Rice University (Houston, Texas, USA) and 26 years of relevant experience.

Additional information for US investors concerning resource estimates

Woodside is an Australian company listed on the Australian Securities Exchange and the New York Stock Exchange. As noted above, Woodside estimates and reports its proved reserves in accordance with SEC regulations, which are also compliant with SPE-PRMS guidelines, and estimates and reports its proved plus probable reserves and 2C contingent resources in accordance with SPE-PRMS guidelines. Woodside reports all petroleum resource estimates using definitions consistent with SPE-PRMS.

The SEC prohibits oil and gas companies, in their filings with the SEC, from disclosing estimates of oil or gas resources other than ‘reserves' (as that term is defined by the SEC). In this announcement, Woodside includes estimates of quantities of oil and gas using certain terms, such as ‘proved plus probable (2P) reserves', ‘best estimate (2C) contingent resources', ‘reserves and contingent resources', ‘proved plus probable', ‘developed and undeveloped', ‘probable developed', ‘probable undeveloped', ‘contingent resources' or other descriptions of volumes of reserves, which terms include quantities of oil and gas that may not meet the SEC's definitions of proved, probable and possible reserves, and which the SEC's guidelines strictly prohibit Woodside from including in filings with the SEC. These types of estimates do not represent, and are not intended to represent, any category of reserves based on SEC definitions, and may differ from and may not be comparable to the same or similarly-named measures used by other companies. These estimates are by their nature more speculative than estimates of proved reserves and would require substantial capital spending over a significant number of years to implement recovery, and accordingly are subject to substantially greater risk of not being recovered by Woodside. In addition, actual locations drilled and quantities that may be ultimately recovered from Woodside's properties may differ substantially. Woodside has made no commitment to drill, and likely will not drill, all drilling locations that have been attributable to these quantities. US investors are urged to consider closely the disclosures in Woodside's most recent Annual Report on Form 20-F filed with the SEC and available on the Woodside website at https://www.woodside.com/investors/reports-investor-briefings and its other filings with the SEC, which are available at www.sec.gov.
