SYDNEY, Feb 17, 2026, 17:28 AEDT — The market has closed.
- Woodside Energy (ASX:WDS) slipped 0.04% to finish at A$25.83 Tuesday.
- The company, in its annual reserves statement, flagged a drop in proved reserves expected by year-end 2025.
- Next up: Woodside’s full-year results and guidance, set for Feb. 24.
Shares of Woodside Energy Group Ltd wrapped up Tuesday nearly flat, slipping just 0.04% to finish at A$25.83 after the company put out its annual reserves update. The stock bounced between A$25.71 and A$25.94 during the session, with 3.04 million shares traded.
Here’s why it matters right now: reserves are basically the inventory. They’re what supports future production, cash flow—and for plenty of investors, they’re the backbone of dividend confidence when commodity prices start to flicker.
The market’s shut now. Next session, focus turns to the reserves update—does it actually sway forecasts for next week’s numbers, or does it just get drowned out by the usual oil chatter and risk sentiment?
Reserves talk isn’t always straightforward. “Proved” reserves, or 1P, refer to what the company figures it can pull out with a solid degree of certainty. Then there’s “proved plus probable” (2P)—that’s 1P plus some extra barrels that come with more risk. “Contingent resources” (2C) are different; these are barrels already discovered but held back, waiting on a final investment decision or other requirements before they shift into the reserves column.
Woodside reported end-2025 proved (1P) reserves at 1,882.1 million barrels of oil equivalent, retreating from last year’s 1,975.7 million. Proved plus probable (2P) reserves edged down as well, coming in at 2,999.5 million boe, compared with 3,092.2 million a year earlier. The company’s 2C contingent resources also slipped, now at 5,795.7 million. Woodside calculated proved reserves life at 8.9 years and 2P reserves life at 14.2 years based on 2025 output. Stripping out the effects of divestments and production, Woodside booked 134.1 million boe of new proved reserves and 141.0 million boe of 2P reserves additions, according to the statement. Acting CEO Liz Westcott called the update something that “underpin our ability to deliver sustained cash flow and long-term value for shareholders.” Woodside
Action stayed muted across the board. The S&P/ASX 200 added 0.24%. Santos ticked down 0.45%, while WTI crude in the U.S. dropped roughly 0.6% during that period.
Woodside shares barely budged, though that reserve update still shapes how investors weigh decline rates and the scale of new sanctioned projects needed to offset them. Even minor changes to booked volumes can flow directly into forecasts and, eventually, influence boardroom debates over capital returns.
The risk is well-known and not just theoretical. Should reserves continue to slip, traders are likely to press even more on output from upcoming LNG and oil developments, with prices that can swing sharply. A prolonged drop in oil and gas prices would also put pressure on reported proved volumes, especially under stricter accounting rules.
Woodside’s next big event lands Feb. 24: the company will put out its 2025 annual report, plus an update on climate and sustainability, and brief investors. Acting CEO Westcott and CFO Graham Tiver are set to run a teleconference at 10:00 a.m. AEDT.
