Woodside secures long term LNG supply deal with Türkiye’s BOTAŞ

Woodside Energy announced on December 28, 2025 that it has signed a binding long term sale and purchase agreement with Türkiye’s state owned pipeline and petroleum transporter BOTAŞ to supply liquefied natural gas beginning in 2030. The contract commits Woodside to deliver about 5.8 billion cubic metres of gas equivalent over the life of the deal, a volume industry sources also describe as roughly 0.5 million tonnes per annum of LNG, with a maximum duration of up to nine years.

The binding sale and purchase agreement converts a non binding heads of agreement the two parties signed in September 2025 into a firm commercial commitment. Woodside said the volumes will be sourced primarily from its under construction three train Louisiana LNG export project on the US Gulf Coast, with the option to draw on the company’s broader global portfolio to meet supply needs. Company materials and industry commentary framed the deal as reinforcing the commercial rationale for Louisiana LNG and as part of Woodside’s broader strategy to expand its US Gulf Coast footprint.

The agreement is significant for Türkiye because BOTAŞ is the country’s principal state buyer and pipeline operator. Securing contracted supply that begins in 2030 gives Ankara a multi year supply stream that industry analysts say will help broaden import diversity and shore up winter period security as Europe and parts of Asia compete for LNG into the next decade. Türkiye’s Energy Minister publicly flagged the new sales arrangements at the World LNG Summit and Awards in Istanbul when announcing recent contractual activity.

Several commercial details remain undisclosed. Woodside and BOTAŞ have not published pricing terms, indexation, the delivery schedule including seasonal profiles, or the delivery terms and regasification logistics. Those omissions leave open questions for market participants about how the cargoes will be scheduled into Türkiye’s import system and how price exposure will be managed.

Market participants are watching the deal as a marker of how major projects will be financed and contracted in the run up to the early 2030s. Long term offtake commitments are widely regarded as central to underpinning capital intensive liquefaction projects. Industry reporting indicates Woodside has been seeking buyers for further equity in the three train Louisiana plant and has been active in winter supply markets, citing a separate arrangement to buy 6 billion cubic metres over 10 winter periods beginning in 2028 from a trading counterparty.

For Woodside the BOTAŞ contract represents entry into a new national market and a step toward monetising its U S Gulf Coast capacity. For Türkiye it locks in a multi year supply stream from a reputable global producer at a time when European and global market tightness is expected to influence winter prices. As the industry moves toward first deliveries in 2030, investors and policymakers will look for clarification on price mechanics and delivery modalities that will determine how material the agreement is for balance sheets and energy security alike.
